Being Certain that Repentance is Accepted
Question

If a person repents and feels that he has fulfilled all the conditions of repentance, can he be sure that his repentance has been accepted, or should he just hope that this is so?
Praise be to Allah.We put the following question to Shaykh Muhammad ibn Salih al-‘Uthaymeen, may Allah preserve him, who answered as follows:
No, he can only hope that this is so. No one can be sure that his repentance has been accepted.
And Allah knows best.
