Wadin bin Ata Khuzai narrated that a man came to the Messenger of Allah (peace be upon him) and said: O Messenger of Allah! We were in the time of ignorance and used to worship idols and kill our children. I had a daughter; when she began to understand things and became happy at my call, one day I called her, and she started following me. While walking, I came to a well belonging to my relatives, which was nearby. I took her hand and pushed her into the well. She kept crying, "Father, father," and these were her last words. (Hearing this) the eyes of the Messenger of Allah (peace be upon him) filled with tears, and he began to weep. One of the companions sitting with the Messenger of Allah (peace be upon him) said: You have saddened the Messenger of Allah. The Prophet (peace be upon him) said: "Wait, they have asked about something that is important for them." Then he said to him: "Tell your story again." He narrated it again until the Prophet's tears flowed and wetted his blessed beard. Then the Prophet (peace be upon him) said to him: "Indeed, Allah the Exalted has forgiven the sins of the time of ignorance, so now begin to do good deeds."
