Mukhtasar Muslim

‘Asim Ahwal says that it was said to Sayyiduna Anas bin Malik (may Allah be pleased with him): “Have you heard from the Messenger of Allah (peace and blessings of Allah be upon him) that there is no alliance (hilf) in Islam?” So Sayyiduna Anas (may Allah be pleased with him) said: “Indeed, the Messenger of Allah (peace and blessings of Allah be upon him) made an alliance between the Quraysh and the Ansar in his house.”
