Abu Zubair says that I asked Sayyiduna Jabir (may Allah be pleased with him) about ghusl, so he said that the people of the tribe of Thaqif came to the Prophet (peace be upon him) and said, "Our area is cold, so what do you command us regarding ghusl?" The Prophet (peace be upon him) said, "I used to pour water over my head three times." He did not say anything beyond this.
