عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) إِنَّ مِنَ السُّنَّةِ أَنْ تَأْخُذَ مِنَ الشَّارِبِ حَتَّى يَبْلُغَ الْإِطَارَ .
6. Ali ibn Ibrahim has narrated from his father from al-Nawfaliy from al-Sakuniy who has said the following: “Abu ‘Abd Allah , has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said, ‘The mustache must be trimmed until the lips become visible.’”
