Question: She was pregnant for [about] a month and a half, and then aborted the pregnancy – unaware of the ruling regarding that; after she learnt about the prohibition [of aborting a pregnancy], she was deeply remorseful. So is there anything required of her?
Response: So long as she repented to Allaah (Subhaanahu wa Ta’aala) from what she had done, then the repentance wipes away what has preceded [of sins]. And Allaah (Subhaanahu wa Ta’aala) says:
So whoever sincerely repents to Allaah (Subhaanahu wa Ta’aala), then Allaah will forgive him his sins.
