Hum se Abdullah bin Muhammad Musandi ne bayan kiya, kaha hum se Sufyan ne bayan kiya, kaha ke main ne Muhammad bin al-Munkadir se suna ke kaha ke main ne Jabir bin Abdullah Ansari razi Allahu anhuma se suna ke hum mein se ek aadmi ke yahan bacha paida hua to unhon ne is ka naam Qasim rakkha. Sahabah ne kaha ke hum tumhari kuniyat Abu al-Qasim nahi rakhein ge aur na teri aankh is kuniyat se pukar kar thandi karein ge. Woh shakhs Nabi Karim salla Allahu alaihi wasallam ki khidmat mein hazir hua aur Aap se is ka zikr kiya. Aap salla Allahu alaihi wasallam ne farmaya ke apne larke ka naam Abd-ur-Rahman rakh lo.
