Sunan an-Nasa'i 5058
It was narrated that 'Abdullah bin Shaqiq said:
"One of the Companions of the Prophet [SAW] 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 of Allah [SAW] forbade us from Al-Irfah,' and we said: 'What is Al-Irfah?' He said: 'To comb your hair every day.'"
