This hadeeth was narrated by al-Tirmidhi, 3713; Ibn Maajah, 121. There is some difference of opinion as to its authenticity. Al-Zayla’i said in Taareekh al-Hidaayah 1/189: “How many ahaadeeth there are which have many narrators and many isnaads, but they are da’eef (weak), such as the hadeeth “If I am someone’s mawla then ‘Ali is his mawla too”.” 

Shaykh al-Islam Ibn Taymiyah said: “As for his saying “If I am someone’s mawla then ‘Ali is his mawla too”, this is not in the books of Saheeh, but it is one of the reports which were narrated by the scholars and concerning whose authenticity the people disputed. It was narrated that al-Bukhaari, Ibraaheem al-Harbi and a group of scholars of hadeeth stated that it is not saheeh… As for the additional material, which is the phrase ‘O Allaah, take as friends those who take him as a friend, and take as enemies those who take him as an enemy,’ etc., this is undoubtedly false.” Manhaaj al-Sunnah, 7/319. Al-Dhahabi said: “As for the hadeeth, “If I am someone’s mawla then ‘Ali is his mawla too”, it has jayyid isnaads.” It was classed as saheeh by al-Albaani in al-Silsilah al-Saheehah, 1750, and he criticized those who said that it is da’eef (weak). 

The fact that this sentence has a saheeh isnaad going back to the Prophet (peace and blessings of Allaah be upon him) – if it is saheeh – cannot under any circumstances be taken as evidence to support what the extremists added to the hadeeth to prove that ‘Ali (may Allaah be pleased with him) takes precedence over all the other Sahaabah, or to slander the Sahaabah and accuse them of usurping his rights. Shaykh al-Islam [Ibn Taymiyah] referred to some of these additions and proved them to be da’eef (weak) in ten places in Manhaaj al-Sunnah. 

There is some difference of opinion as to the meaning of the hadeeth. Whatever the meaning, it does not contradict that which is proven and well-known from the saheeh ahaadeeth which state that the best of this ummah is Abu Bakr and that he was the most deserving of being the khaleefah; then he was followed by ‘Umar, then ‘Uthmaan – may Allaah be pleased with them all. Proof of the virtue of a specific Sahaabi does not means that he is the best of them, and that does not contradict the fact that Abu Bakr is the best of them as is affirmed in the chapters on ‘aqeedah. 

One of the meanings that have been suggested for this hadeeth is as follows: 

“It was said that its meaning is, ‘whomever I took as a friend, ‘Ali will also take him as a friend as opposed to an enemy, and whomever I used to love, ‘Ali will also love him.’ And it was said that its meaning is, ‘whoever took me as a friend, ‘Ali will also take him as a friend.’ This was quoted by al-Qaari’ from some of his scholars. Al-Jazari said in al-Nihaayah: ‘The word mawla is frequently mentioned in the hadeeth, and this is a name that is applied to many. It may refer to a lord, to an owner, to a master, to a benefactor, to one who frees a slave, to a supporter, to one who loves another, to a follower, to a neighbour, to a cousin (son of paternal uncle), to an ally, to an in-law, to a slave, to a freed slave, to one to whom one has done a favour. Most of these meanings are referred to in various ahaadeeth, so it is to be understand in the manner implied by the context of the hadeeth in which it is mentioned. Everyone who is in charge of some matter or is taking care of it is the mawla of that thing. The word mawla mentioned in this hadeeth may refer to most of the meanings indicated above. Al-Shaafa’i (may Allaah have mercy on him) said: What is meant by that is the bonds of Islam, as in the aayah (interpretation of the meaning): 

‘That is because Allaah is the Mawlaa (Lord, Master, Helper, Protector) of those who believe, and the disbelievers have no Mawlaa (lord, master, helper, protector)’

[Muhammad 47:11]

Al-Teebi said: it is incorrect to interpret the mawla as referring to the imam who conducts the affairs of the believers, because the only person who was in charge of the Muslims’ affairs during the lifetime of the Prophet (peace and blessings of Allaah be upon him) was the Prophet himself and no one else, so the word mawla must be interpreted as referring to love, the bonds of Islam and so on.”
