Hum se Sadaqah bin Fadl ne bayan kiya, kaha hum ko Sufyan bin Uyaynah ne khabar di, in se Ibn al-Munkadir ne bayan kiya aur in se Jabir razi Allahu anhu ne bayan kiya ke hum mein se ek sahab ke yahan bacha paida hua to unhon ne is ka naam Qasim rakkha. Hum ne in se kaha ke hum tum ko Abu al-Qasim keh kar nahi pukarein ge (kyunke Abu al-Qasim Nabi Karim salla Allahu alaihi wasallam ki kuniyat thi) aur na hum tumhari izzat ke liye aisa karein ge. In sahab ne is ki khabar Nabi Karim salla Allahu alaihi wasallam ko di, to Nabi Karim salla Allahu alaihi wasallam ne farmaya ke apne bete ka naam Abd-ur-Rahman rakh le.
