Abu Qilabah (may Allah have mercy on him) reports from a man of Banu Amir. Ayyub (may Allah have mercy on him) said: I met him and asked him, and he told me that a man had narrated to him that he came to Madinah in search of camels. Then he went to the Messenger of Allah (peace and blessings be upon him), and he narrated the hadith in the same way.
