مسند أحمد

It was narrated that Masrooq bin al-­Ajda' said: I met 'Umar bin al­-Khattab and he said: Who are you? I said: Masrooq bin al­-Ajda'. 'Umar said: I heard the Messenger of Allah (ﷺ) saying, `Al- Ajda' is a devil [i.e. the word Al-­Ajda' has a bad meaning]; rather you are Masrooq bin ‘Abdur-Rahman. 'Amir said: I saw his name written in the Deewan; Masrooq bin ‘Abdur-­Rahman. I said: What is this? He said. This is what ‘Umar رضي الله عنه called me.
