Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ آدَمَ قَالَ حَدَّثَنَا ابْنُ مُبَارَكٍ عَنْ مَعْمَرٍ وَيُونُسَ عَنِ الزُّهْرِيِّ عَنْ عَبْدِ الرَّحْمَنِ بْنِ عَبْدِ اللَّهِ بْنِ كَعْبِ بْنِ مَالِكٍ عَنْ كَعْبٍ قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا سُرَّ اسْتَنَارَ وَجْهُهُ حَتَّى كَأَنَّ وَجْهَهُ شِقَّةُ قَمَرٍ وَكُنَّا نَعْرِفُ ذَلِكَ فِيهِ.
English Translation
Yahya ibn Adam narrated to us: Ibn al-Mubarak narrated to us, from Ma'mar and Yunus, from al-Zuhri, from Abd al-Rahman ibn Abdullah ibn Ka'b ibn Malik, from Ka'b, who said: When the Messenger of Allah, peace and blessings be upon him, was pleased, his face would light up until his face was like a piece of the moon, and we would recognize that in him.
