When the battle of al-Khandaq came to an end and the Prophet (s) came back to Medina, Gabriel came down to him at noon and ordered him to go to fight the Jews of bani Quraydha who had broken their covenant with the Prophet (s). The Prophet (s) ordered the Muslims to get ready and to offer Asr Prayer there. When the Prophet (s) blockaded the Jews, they said to him, ‘Send us Abu Lubaba to counsel with him our affair.’ The Prophet (s) said, ‘O Abu Lubaba, go to your allies!’ He went to them and they said to him, ‘O Abu Lubaba, what do you see if we submit to Muhammad?’ He said to them, ‘Submit to him but know well that you will be killed.’ And he pointed to his throat. Then he felt sorry for that and said, ‘I have betrayed Allah and His messenger.’ He went to the mosque, tied a rope around his neck and fastened it to the column of the mosque which was called “the column of repentance” later on. He said, ‘I will not untie the rope until I die or that Allah will accept my repentance.’ When the Prophet (s) was informed of that, he said, ‘If he came to us, we would pray Allah to forgive him but as he has turned to Allah so Allah is worthier of him.’ Abu Lubaba fasted during the day and ate in the night what could keep him alive only. His daughter brought him food and untied him when needing to go to the water closet. Some time later, Allah revealed to the Prophet (s) while he was in the house of his wife Umm Salama that Abu Lubaba’s repentance had been accepted. The Prophet (s) said to Umm Salama, ‘O Umm Salama, Allah has accepted the repentance of Abu Lubaba.’ She said to him, ‘O messenger of Allah, let you tell him that!’ The Prophet (s) said to her, ‘Let you do that!’ She took her head out of the room and said, ‘O Abu Lubaba, Allah has accepted your repentance.’ He said, ‘Praise be to Allah!’ The Muslims jumped to untie him but he said, ‘No, by Allah, until the messenger of Allah unties me.’ The Prophet (s) came to him and said, ‘O Abu Lubaba, Allah has accepted your repentance that if you are born today it will suffice you.’ Abu Lubaba said, ‘O messenger of Allah, do I pay all my money as charity?’ The Prophet (s) said, ‘No, you do not.’ He said, ‘Two thirds of it?’ The Prophet (s) said, ‘No.’ He said, ‘A half of it?’ The Prophet (s) said, ‘No.’ Then he said, ‘One third?’ The Prophet (s) said, ‘Yes, you do.’[1]
