من أطاع عليا فقد أطاعني، ومن عصى عليا فقد عصاني، ومن عصاني فقد عصى الله. ومن أحب عليا فقد أحبني، ومن أحبني فقد أحب الله. ومن أبغض عليا فقد أبغضني، ومن أبغضني فقد أبغض الله. لا يحبك إلا مؤمن، ولا يبغضك إلا كافر أو منافق.
Whoever obeys ‘Ali has surely obeyed me. And whoever disobeys me has surely disobeyed Allah. And whoever loves ‘Ali has surely loved me. And whoever loves me has surely loved Allah. Whoever hates ‘Ali has surely hated me. And whoever hates me has surely hated Allah. Only a believer loves you. And only a disbeliever or hypocrite hates you.
This hadith is narrates by Ya’la ibn Murrah and Abu Dharr radiya Llahu ‘anhuma.
The Hadith of Ya’la ibn Murrah
Ibn ‘Adi and Ibn ‘Asakir narrate — Muhammad ibn Jafar ibn Yazid al Matiri narrated to us — Ibrahim ibn Sulaiman al Nahmi al Kufi narrated to us — ‘Ubadah ibn Ziyad narrated to us — ‘Umar ibn Sa’d narrated to us — from ‘Umar ibn ‘Abdullah al Thaqafi — from his father — from his grandfather — Ya’la ibn Murrah al Thaqafi who said, “I heard the Messenger of Allah salla Llahu ‘alayhi wa sallam say,” and then he mentioned the hadith.
Ibn ‘Adi says that ‘Ubadah ibn Ziyad has munkar (unacceptable) ahadith on the subject of fadaʾil (virtues).
Ibrahim ibn Sulaiman al Nahmi is da’if (weak).
‘Umar ibn ‘Abdullah ibn Ya’la ibn Murrah al Thaqafi al Kufi is da’if (weak). In fact, he is matruk (suspected of forgery).
His father is da’if (weak).
Al Bukhari says the hadith of ‘Umar ibn Sa’d al Basri are inauthentic.
The Hadith of Abu Dharr
Yahya ibn Ya’la is al Aslami. He is da’if (weak).
Ibn Hibban is the only person to regard Muawiyah ibn Tha’labah as a thiqah (reliable).
Al Hakim authenticated the hadith, but he made a mistake. Furthermore, I noticed al Albani mention the hadith and rule it to be mawdu’ (fabricated). As al Albani stated, this ruling is correct.
 Ibn ‘Adi: al Kamil, 4/349; ibn ‘Asakir: Tarikh Dimashq, 42/270.
 Ibn Hajar: Lisan al Mizan, 1/65.
 Al ‘Uqayli: al Du’afaʾ, 3/262.
 In al Kamil, the name appears as ‘Taghlib’. However, the correct name is as I have mentioned above.
 Ibn ‘Adi: al Kamil, 7/233.
 Al Albani: Silsilat Ahadith al Da’ifah, hadith no. 4892.
