Ash-Shama'il al-Muhammadiyya 35

‘Abdallah b. Mughaffal said God’s messenger forbade combing the hair except every second day. Tirmidhi, Abu Dawud and Nasa'i transmitted it.

وَعَن عبد الله بن مغفَّل قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنِ التَّرَجُّلِ إِلَّا غِبًّا. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُد وَالنَّسَائِيّ
