It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that he said: "the Messenger of Allah (peace and blessings be upon him) set out towards Banu Lihyan and put the Ka'bah behind him. Then he (peace and blessings be upon him) said: 'O Jabir bin Abdullah!' I came to him (peace and blessings be upon him), and he (peace and blessings be upon him) sent me on an errand of his. Then I came back to him (peace and blessings be upon him) and said: 'I went to those people and I did such and such.' But he (peace and blessings be upon him) gave me no reply. I went away and said (to myself): 'Perhaps I did not understand the Messenger of Allah (peace and blessings be upon him).' So I came to him (peace and blessings be upon him) again and said: 'I went to them and I did such and such.' Then he (peace and blessings be upon him) said: 'I was praying.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ibrahim bin Muhajir except Isra'il, and Mus'ab bin al-Miqdam is alone in narrating it."
