A man had his beard shaved, and said (to the barber), “I will pay you later, I owe you.” Then Allaah guided him and he began to follow the Islamic rulings [i.e., he grew a beard]. Should he pay the barber or not?
Praise be to Allaah.
We put this question to Shaykh Muhammad ibn Saalih al-‘Uthaymeen, may Allaah preserve him, and he answered as follows:
He should tell him: “I am not going to give you the money, because it was (in payment for) a haraam deed,” and he should give it away in charity. And Allaah knows best.
