عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ سَدَلَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَاصِيَتَهُ مَا شَاءَ اللَّهُ أَنْ يَسْدُلَهَا ثُمَّ فَرَقَ بَعْدُ
Sayyiduna Anas (may Allah be pleased with him) narrates that as long as Allah willed, the Noble Prophet (peace and blessings be upon him) kept his hair straight, then he started parting it.
