مُسْنَدِ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ

Musnad `Umar b. al-Khattab (ra)
Musnad Ahmad 211
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.
حَدَّثَنَا أَبُو النَّضْرِ، حَدَّثَنَا أَبُو عَقِيلٍ، حَدَّثَنَا مُجَالِدُ بْنُ سَعِيدٍ، أَخْبَرَنَا عَامِرٌ، عَنْ مَسْرُوقِ بْنِ الْأَجْدَعِ، قَالَ لَقِيتُ عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ فَقَالَ لِي مَنْ أَنْتَ قُلْتُ مَسْرُوقُ بْنُ الْأَجْدَعِ فَقَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ الْأَجْدَعُ شَيْطَانٌ وَلَكِنَّكَ مَسْرُوقُ بْنُ عَبْدِ الرَّحْمَنِ قَالَ عَامِرٌ فَرَأَيْتُهُ فِي الدِّيوَانِ مَكْتُوبًا مَسْرُوقُ بْنُ عَبْدِ الرَّحْمَنِ فَقُلْتُ مَا هَذَا فَقَالَ هَكَذَا سَمَّانِي عُمَرُ‏.‏
