My son is four and a half years old. Is it permissible for me to beat him with a non-harmful beating if he does not memorize the surahs of the Qur'an?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: I have a son who is four and a half years old, and I am teaching him the Qur'an at home, but he does not memorize it. His question is: Is it permissible for me to beat him with a non-harmful beating?

Answer:
Four and a half, yes. This is not what is known as education. When he reaches the age of discernment, meaning seven years old, then teach him. But at four and a half or four years old, this is torment for him, and he will not benefit.
