Arabic (Original)
حَدَّثَنَا سُفْيَانُ عَنِ ابْنِ أَبِي نَجِيحٍ عَنْ مُجَاهِدٍ قَالَ شَهِدَ ابْنُ عُمَرَ الْفَتْحَ وَهُوَ ابْنُ عِشْرِينَ سَنَةً وَمَعَهُ فَرَسٌ حَرُونٌ وَرُمْحٌ ثَقِيلٌ فَذَهَبَ ابْنُ عُمَرَ يَخْتَلِي لِفَرَسِهِ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ عَبْدَ اللَّهِ إِنَّ عَبْدَ اللَّهِ.
English Translation
Sufyan narrated to us, from Ibn Abi Najih, from Mujahid, who said: Ibn 'Umar witnessed the Conquest [of Makkah] when he was twenty years old, having with him a restive horse and a heavy spear. Ibn 'Umar went to gather fodder for his horse, so the Messenger of Allah, peace and blessings be upon him, said: "Indeed 'Abdullah, indeed 'Abdullah [is dutiful]."
