A woman came to Prophet Musa and said: "I committed a grave sin. Please pray to Allah that He forgives me."

Prophet Musa: "What did you do?"

Woman: "I committed fornication and later gave birth to a boy whom I killed."

Prophet Musa: "Go away from here, you wicked woman, lest a fire from Heaven destroys us all because of your sin!

The woman left broken-hearted.

Then Angel Jibril descended and asked: "O Musa, why have you turned away a repentant woman? Have you not found anyone worse than her?"

Prophet Musa: "Who can be worse than her?"

Angel Jibril: "The one who abandons salah intentionally and persistently."
