عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُصُّ شَارِبَهُ وَكَانَ أَبُوكُمْ إِبْرَاهِيمُ مِنْ قَبْلِهِ يَقُصُّ شَارِبَهُ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both), he says: The Messenger of Allah (peace and blessings be upon him) used to trim his moustache, and before him, your father Ibrahim (peace be upon him) also used to trim his moustache.
