He said: Abu Hafs Umar b. Muhammad, commonly known as Ibn al-Zayyat, may ALLAH (SWT) bless him with mercy, reported to me from Abu ALI Muhammad b. Hammam al- Iskafi, from Abdullah b. Ja'far al-Himyari, from Abdullah b. Muhammad b. Isa, from his father, from Abdullah b. al-Mughaira, from Ibn Maskan, from Umar b. Zayd, who reported that:
ABU ABDULLAH JA'FAR B. MUHAMMAD (ASWS), peace be upon him, said: When the PROPHET (SAWW) , peace be upon him and his progeny, arrived at the middle of Qudaid (near Makkah), he said to ALI BIN ABI TALIB (ASWS), peace be upon him:
"O ALI (ASWS) , I prayed to ALLAH (SWT) for (a firm bond of) love between me and you, and He granted, and I prayed to Him to establish brotherhood between you and me, and He granted, and I prayed unto him that He make you my successor, and He granted."
A man stood up from the people and remarked: "By ALLAH (SWT), a (small) measure of dates from an old, coarse sack is better than what MOHAMMAD (SAWW) prayed for from his Lord. Why did he not ask for angel to come and help him against his enemy, or a treasure to help him keep away his paucity?"
Then ALLAH (SWT) revealed this verse: 'Perhaps you feel like giving away some of what has been revealed to you, and your chest is straitened for it, because they say: Why has a treasure not been sent down to him or an angel come down with him? Surely, you are only a warner, and ALLAH (SWT) is the Trustee over all things.' (11:12)
