The ruling on a person in ihram combing his head and forgetting to shorten the hair

Question:
He says: I performed 'Umrah four days ago, and I combed my hair between the tawaf and the sa'y while forgetting that I was in ihram. After finishing the 'Umrah, I came out of the state of ihram, but I forgot to shorten the hair. I did not remember until three days later, when I then shortened it. What is the ruling in this matter?

Answer:
It is permissible for a person in ihram to comb his head and to take a bath, washing his head. This is permissible, but he must do so gently, without combing his head forcefully for fear that some hair might fall out. Rather, he combs his head gently. It is permissible for a person in ihram to comb his head, and it is permissible for him to take a bath and wash his head; there is nothing wrong with it. As for what you did, where you forgot to shorten the hair for three days and then, when you realized it, you shortened it, the intended purpose was achieved, and praise be to Allah.
