As humans we are weak, and we can and do make mistakes. We commit sins. After committing a sin,we often think that this is not the right time to ask Allah for forgiveness. But there is no bad or inappropriate time to ask Allah for forgiveness,even if we are halfway in our sin. Allah is All-Forgiving, All Merciful. He knows our weaknesses and our shortcomings. His door of forgiveness is always open. No matter how awful our sin,Allah is always ready to hear and accept our repentance. So if we commit a sin,we should not sit back and wait. We should immediately do these things because if Allah wills, our sins will be wiped away.
