A man came to Ali and said, "Commander of the Faithful, I am unable to fulfill my contract for emancipation, so help me."Ali replied, "Shall I teach you words the Messenger of Allah ﷺ taught me? Even if you owed a debt the size of Mount Sir in gold coins, Allah would settle it for you."I said, "Yes, please."He said, "Say, 'O Allah, suffice me with what You have made lawful so I have no need of what You have forbidden, and enrich me through Your bounty so I have no need of anyone besides You.'"
أتى عليا رجل فقال: يا أمير المؤمنين إني عجزت عن مكاتبتي فأعني. فقال علي: ألا أعلمك كلمات علمنيهن رسول الله ﷺ ولو كان عليك مثل جبل صير دنانير، لأداه الله عنك. قلت: بلى قال: قل: اللهم اكفني بحلالك عن حرامك، واغنني بفضلك عمن سواك.
Reported by Tirmidhi (3563), Abdullah bin Ahmad in Zawaid al-Musnad (1319), and Hakim (1/538) - and from him Bayhaqi in Daawat al-Kabir (303) - all of them via Abu Muawiya, from Abdul-Rahman bin Ishaq Qurashi, from Sayyar Abu Hakam, from Abu Waail, who mentioned it.Its chain is hasan because of Abdul-Rahman bin Ishaq Qurashi. He is described as Qurashi by Abdullah bin Ahmad, Hakim, and Bayhaqi, and he is Abdul-Rahman bin Ishaq bin Abdullah bin Harith bin Kinanah Amiri Qurashi, their client, of Madinah. Ibn Abu Hatim mentioned in al-Jarh wal-Tadil (5/212) that he narrates from Sayyar Abu Hakam, and if he is indeed the Qurashi, then his hadith is hasan.Tirmidhi said, "This is a hasan gharib hadith."Hakim said, "This is a hadith sahih in its chain."As for his saying "Mount Sayr," it is the name of a mountain belonging to the tribe of Tayy, and it is also said as "Sur" or "Sayr."
