Muhammad bin Ali (may Allah have mercy on him) said: The Prophet (peace and blessings be upon him) was washed three times with lote-tree leaves (sidr); he (peace and blessings be upon him) was washed while wearing a shirt; and he (peace and blessings be upon him) was washed with the water of al-Ghars, a well at Quba that belonged to Sayyiduna Sa'd bin Khaythamah (may Allah be pleased with him), and he (peace and blessings be upon him) used to drink its water. Sayyiduna Ali (may Allah be pleased with him) took charge of washing his (peace and blessings be upon him) lower body, Sayyiduna al-Fadl (may Allah be pleased with them both) held him against his chest, and Sayyiduna al-Abbas (may Allah be pleased with him) was pouring the water. Sayyiduna al-Fadl (may Allah be pleased with them both) began saying: Relieve me, you have cut my aorta; I feel something heavy pressing down on me.
