عَنِ ابْنِ عَبَّاسٍ
قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُصُّ أَوْ يَأْخُذُ مِنْ شَارِبِهِ وَكَانَ إِبْرَاهِيمُ خَلِيلُ الرَّحْمَنِ صَلَوَاتُ الرَّحْمَنِ عَلَيْهِ يَفْعَله
Ibn Abbas said the Prophet (sallallahu alayhi wa sallam) used to clip or take something off his moustache, and Abraham the friend of the Compassionate One used to do it.
