It is narrated from Umm Atiyyah (may Allah be pleased with her) that the Messenger of Allah (peace be upon him) said at the time of giving his daughter a bath: "Give her a bath three or five times, and if you deem it appropriate, you may do so even more than that. Mix lote tree leaves in the bathing water, and at the end, use camphor or something of camphor."
