وَ فِي رِوَايَةِ عَبْدِ اَللَّهِ بْنِ سِنَانٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ : «يَسْتَغْفِرُ اَللَّهَ تَعَالَى».
Hadith.2742 - Ishaq ibn Ammar narrated from Abu Ibrahim (as): I asked him about a man performing tamattu‘ (Hajj) who forgets to trim his hair until he has already entered the state of ihram for Hajj.

"He should seek forgiveness from Allah (swt), the Exalted."
