English Translation
Abd al-Rahman ibn Ka'b ibn Malik, who was the guide of his father after he lost his sight, narrated from his father Ka'b ibn Malik that whenever he heard the call on Friday, he would invoke mercy upon As'ad ibn Zurarah. He asked him about it, and Ka'b said: 'Because he was the first to lead us in Friday prayer in Hazm al-Nabit, in Harrat Bani Bayadah, in a depression called al-Khadamat.' He asked: 'How many were you that day?' He said: 'Forty.' Jarir ibn Hazim and Muhammad ibn Salamah also narrated it from Ibn Ishaq. When Ibn Ishaq mentions his direct hearing in a narration and the narrator is trustworthy, the chain is sound. This hadith has a good and authentic chain. Another hadith has been reported regarding this matter but it cannot be used as proof.
