It is narrated from Hazrat Aisha (may Allah be pleased with her) that on the occasion of the incident of Ifk, the Prophet (peace and blessings be upon him) said to me: O Aisha! If you have intended a sin, then seek forgiveness from Allah, because repentance from sin is remorse and seeking forgiveness.
