عَنِ ابْنِ عَبَّاسٍ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُصُّ أَوْ يَأْخُذُ مِنْ شَارِبِهِ وَكَانَ إِبْرَاهِيمُ خَلِيلُ الرَّحْمَنِ صَلَوَاتُ الرَّحْمَنِ عَلَيْهِ يَفْعَله. رَوَاهُ التِّرْمِذِيّ

‘Abdallah b. Ja'far said

The Prophet waited three days before visiting the family of Ja'far (Ja'far b. Abu Talib was killed at Mu'ta in the year 7 A.H). He said, “Do not weep for my brother after today,” and then said, “Call my brother’s children to me.” When we had been brought like a number of chickens he said, “Call me a barber,” and then ordered him to shave our heads.Abu Dawud and Nasa’i transmitted it.
