Lady Umm Salamah (may Allah be pleased with her), the wife of the Prophet (peace be upon him), said that a woman came to the Prophet (peace be upon him) and asked: "I tie my hair in a braid on my head, what should I do?" He replied: "Pour three handfuls of water over your head, and after pouring each handful, rub (your hair)." (That is, rub the hair so that the water reaches the roots.)
