Sayyidah Umm Ismah al-Awsiyyah, who belonged to the Qays tribe, narrates: The Prophet (peace and blessings be upon him) said: "When a servant commits a sin, the angel appointed over him holds back from recording that sin for three hours. If that servant seeks forgiveness from Allah Almighty for that sin during those hours, that sin will not be held against him on the Day of Resurrection."
Al-Tabarani recorded it; its chain contains a narrator, Abu Mahdi Sa'id bin Sinan, who is matruk (abandoned).
