It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: Some people used to engage in very intense worship, but the Noble Prophet (peace and blessings be upon him) forbade them and said: By Allah! Indeed, I am the one among you who knows Allah the most and fears Him the most. You should perform as many deeds as you have the strength for, for indeed Allah will not tire until you tire.
