Virtues of Abu Bakr Siddeeq Radhiallahu Anhu

[al-Tawbah 9:40]
And ‘Amr ibn al-‘Aas (may Allaah be pleased with him) narrated that the Prophet (peace and blessings of Allaah be upon him) appointed him as the commander of the army of Dhaat al-Salaasil. He said: So I came to him and said, “Which of the people is dearest to you?” He said, “ ‘Aa’ishah.” I said, “Who among men?” He said, “Her father.” I said, “Then who?” He said, “Then ‘Umar ibn al-Khattaab,” and he mentioned some other men.
Narrated by al-Bukhaari, 3662; Muslim, 2384.
Another of his virtues is the fact that the Prophet (peace and blessings of Allaah be upon him) appointed him to lead the prayers in his stead at the end of his life, when he fell sick with his final illness, and he rebuked those who objected to this and said, “Tell Abu Bakr to lead the people in prayer.”
Narrated by al-Bukhaari, 683; Muslim 418.
And it was narrated from Anas ibn Maalik (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) climbed Uhud with Abu Bakr, ‘Umar and ‘Uthmaan, and it trembled beneath them. He said, ‘Stand firm, O Uhud, for there is no one on you but a Prophet, a Siddeeq and two martyrs.”
Narrated by al-Bukhaari, 3675.
It was narrated that Ibn ‘Umar (may Allaah be pleased with him) said: “We used to compare the people as to who was better at the time of the Messenger of Allaah (peace and blessings of Allaah be upon him). We used to regard Abu Bakr as the best, then ‘Umar ibn al-Khattaab, then ‘Uthmaan ibn ‘Affaan (may Allaah be pleased with them).” Narrated by al-Bukhaari, 3655. According to another report he said: “At the time of the Prophet (peace and blessings of Allaah be upon him) we did not regard anyone as equal with Abu Bakr, then ‘Umar, then ‘Uthmaan, then we left the companions of the Prophet (peace and blessings of Allaah be upon him) and we did not differentiate between them.” Al-Bukhaari, 2679.
narrated that Muhammad ibn al-Hanafiyyah (who was the son of ‘Ali ibn Abi Taalib) said: “I said to my father, ‘Which of the people was the best after the Messenger of Allaah (peace and blessings of Allaah be upon him)?’ He said, ‘Abu Bakr.’ I said, ‘Then who?’ He said, ‘Then ‘Umar.’ I was afraid that he would say ‘Uthmaan. I said, ‘Then is it you?’ He said, ‘I am only one of the Muslims.’”
Narrated by al-Bukhaari, 3671.
It was narrated that ‘Ali (may Allaah be pleased with him) said: “No one is brought to me who regards me as superior to Abu Bakr and ‘Umar but I will punish him with a beating like a fabricator.” Shaykh al-Islam Ibn Taymiyah said: It was narrated that he used to speak from the minbar of Kufa and say that the best of this ummah after our Prophet was Abu Bakr, then ‘Umar. This was narrated from him via more than eighty isnaads, and it was narrated by al-Bukhaari and others. Hence the earlier Shi’ah all used to agree that Abu Bakr and ‘Umar were superior, as has been mentioned by more than one. Manhaaj al-Sunnah, 1/308
It was narrated from Abu Juhayfah that ‘Ali (may Allaah be pleased with him) ascended the minbar and praised and glorified Allaah and sent blessings upon the Prophet (peace and blessings of Allaah be upon him), then he said: “The best of this ummah after its Prophet is Abu Bakr. The second is ‘Umar (may Allaah be pleased with him), and after that, whoever Allaah wants to be good will be good.”
Narrated by Imam Ahmad in his Musnad, 839. And Shaykh Shu’ayb al-Arna’oot said: its isnaad is qawiy.
 
Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said: “No one among the respectable Muslim scholars has said that ‘Ali was more knowledgeable or had more understanding of Islam than Abu Bakr and ‘Umar, or even than Abu Bakr alone. Those who claim that there is consensus on that are among the most ignorant of people and the greatest liars. Rather, more than one of the scholars have stated that there is scholarly consensus that Abu Bakr al-Siddeeq was more knowledgeable than ‘Ali, such as Imam Mansoor ibn ‘Abd al-Jabbaar al-Sam’aani al-Marwadhi, one of the leading scholars of the Sunnah among the companions of al-Shaafa’i, who mentioned in his book Taqweem al-Adillah ‘ala’l-Imam that there was consensus among the scholars of the Sunnah that Abu Bakr was more knowledgeable than ‘Ali. I do not know of anyone among the famous imams who disputes this point. How could it be otherwise when Abu Bakr al-Siddeeq used to issue rulings and commands and prohibitions, and pass judgements, and deliver khutbahs in the presence of the Prophet (peace and blessings of Allaah be upon him), as he used to do when he and Abu Bakr would go out to call the people to Islam, and when they migrated together, and on the day of Hunayn, and on other occasions, when the Prophet (peace and blessings of Allaah be upon him) remained silent and approved of what Abu Bakr said; no one else enjoyed such status. When the Prophet (peace and blessings of Allaah be upon him) consulted with the wise and knowledgeable men among his companions, he would consult Abu Bakr and ‘Umar first, because they were the first to speak about matters of Islam in the presence of the Messenger (peace and blessings of Allaah be upon him) before the rest of his companions; for example when he consulted them about the prisoners of Badr, the first ones who spoke about that were Abu Bakr and ‘Umar, and this also happened on other occasions… In Saheeh Muslim it is narrated that the companions of the Prophet (peace and blessings of Allaah be upon him) were with him on a journey and he said: “If the people obey Abu Bakr and ‘Umar, they will be guided aright.” And it was narrated from Ibn ‘Abbaas that he used to give his fatwas based on the Book of Allaah, and if he could not find anything then he would look at the Sunnah of the Messenger of Allaah (peace and blessings of Allaah be upon him), then if he could not find anything he would refer to the fatwas of Abu Bakr and ‘Umar, then if he did not find anything he would refer to the fatwas of ‘Uthmaan and ‘Ali – and Ibn ‘Abbaas was the habr al-ummah(scholar of the ummah) and the most knowledgeable of the Sahaabah of his time, and he would consult the words of Abu Bakr and ‘Umar and give them precedence over the words of anyone else among the Sahaabah. And it was proven that the Prophet (peace and blessings of Allaah be upon him) prayed for Ibn ‘Abbaas and said, “O Allaah, cause him to understand the religion of Islam and teach him the correct interpretation (of the Qur’aan).”
Majmoo’ al-Fataawa, 4/398
It was narrated from Muhammad ibn Jubayr ibn Mut’im that his father said: “A woman came to the Prophet (peace and blessings of Allaah be upon him) and he told her to come back later. She said, ‘What if I come back and do not find you?’ as if she was referring to death. He (peace and blessings of Allaah be upon him) said, ‘If you do not find me, then go to Abu Bakr.’” (Narrated by al-Bukhaari, 3659).
It was narrated that Ibn Mas’ood said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Take as your leaders those who come after me, Abu Bakr and ‘Umar.’” (Narrated by al-Tirmidhi, 3805; classed as saheeh by al-Albaani).
It was narrated that Ibn ‘Umar (may Allaah be pleased with them both) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Whilst I was standing by a well, drawing water from it, Abu Bakr and ‘Umar came. Abu Bakr took the bucket and drew one or two buckets, but there was some weakness in his drawing. May Allah forgive him. Then ‘Umar bin Al-Khattaab came and the bucket turned into a very large one in his hands. I had never seen such a mighty person as he in doing such hard work till all the people drank to their satisfaction and watered their camels that knelt down there.’” (Narrated by al-Bukhaari, 3676).
Ibn Hajar said in his commentary on this hadeeth:
“Whilst I was standing by a well” means, in a dream. “Drawing water from it” means, filling a bucket with water. “He drew one or two buckets (dhanooban aw dhanoobayn)”: dhanoob refers to a large bucket when it is full of water. It seems to me that this refers to the major conquests which took place during his reign (as khaleefah), which numbered three. Hence the hadeeth does not refer to the number of buckets in the case of ‘Umar, rather it describes his drawing of water as ‘mighty’, referring to the many conquests that would occur during his reign as khaleefah. And Allaah knows best.
Al-Shaafa’i mentioned the interpretation of this hadeeth in al-Umm, where after quoting it he said: The meaning of the phrase “but there was some weakness in his drawing” is that his time of leadership was short, because of his untimely death and the fact that the war against the apostates (ahl al-riddah) kept him from reaching the level of conquests attained by ‘Umar during his lengthy reign as khaleefah.
It was narrated that ‘Aa’ishah said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said to me when he was sick, ‘Call Abu Bakr for me, your father and your brother, so that I may dictate a letter. For I am worried lest someone who is ambitious says that he is more entitled to the position of leadership, but Allaah and the believers will not accept anyone other than Abu Bakr.’” (Narrated by Muslim, 2387).
During his final illness, the Prophet (peace and blessings of Allaah be upon him) appointed Abu Bakr al-Siddeeq to lead the Muslims in prayer and he did not accept anyone else to take his place. The fact that he was appointed to take his place in the case of minor leadership (leading the prayers) indicates that he would succeed him in the case of major leadership (as imaam or khaleefah).
