It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when the polytheists attacked the Noble Prophet (peace and blessings be upon him), while he (peace and blessings be upon him) was accompanied by seven Ansar and two Qurayshis, the Prophet (peace and blessings be upon him) said: Who will drive these polytheists away from us? Whoever does so will be my companion in Paradise as a result of this deed. In response, one of the Ansar stepped forward and kept fighting the enemy, defending the Prophet (peace and blessings be upon him), until he was martyred. When the polytheists attacked the Prophet (peace and blessings be upon him) again, he said again: Who is there who will drive these polytheists away from us and keep them at bay? As a result of this deed, he will be my companion in Paradise. In this way, all seven Ansar were martyred. The Messenger of Allah (peace and blessings be upon him) then said to his two Qurayshi companions: We have not done justice to our brothers.
