It was narrated that 'Abdullah bin Shaqiq said:

"One of the Companions of the Prophet (ﷺ) [ﷺ] was a governor in Egypt, and one of his companions came to him and found him with unkempt, wild hair. He said: 'How come I see you with wild hair when you are a governor?' He said: 'The Prophet (ﷺ) of Allah [ﷺ] forbade us from Al-Irfah,' and we said: 'What is Al-Irfah?' He said: 'To comb your hair every day.'"

أَخْبَرَنَا إِسْمَاعِيلُ بْنُ مَسْعُودٍ، قَالَ حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، عَنْ كَهْمَسٍ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، قَالَ كَانَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم عَامِلاً بِمِصْرَ فَأَتَاهُ رَجُلٌ مِنْ أَصْحَابِهِ فَإِذَا هُوَ شَعِثُ الرَّأْسِ مُشْعَانٌّ قَالَ مَا لِي أَرَاكَ مُشْعَانًّا وَأَنْتَ أَمِيرٌ قَالَ كَانَ نَبِيُّ اللَّهِ صلى الله عليه وسلم يَنْهَانَا عَنِ الإِرْفَاهِ ‏.‏ قُلْنَا وَمَا الإِرْفَاهُ قَالَ التَّرَجُّلُ كُلَّ يَوْمٍ ‏.‏
