The Messenger (blessings and peace of Allah be upon him) was washed in his garments. When the Sahaabah (may Allah be pleased with them) differed as to whether they should remove his clothes or not, they heard a voice calling out from inside the house, saying: “Wash the Prophet (blessings and peace of Allah be upon him) in his garments; pour water over him and wash him in his garments, blessings and peace be upon him.” Then they shrouded him in three pieces of white cotton cloth, among which there was no chemise or turban, as it says in the hadeeth of ‘Aa’ishah (may Allah be pleased with her. Then the people offered the funeral prayer for him (blessings and peace of Allah be upon him) individually. They were not led in prayer by any imam; rather each person entered and prayed for him in the mosque. End quote.
