‘Abdallah b. Buraida told that a man asked Fadala b. ‘Ubaid why it was he saw him dishevelled and he replied that God's messenger had forbidden them to indulge much in luxury. He asked why it was he saw him unshod and he replied that God's messenger used to command them to go barefoot at times.
Abu Dawud transmitted it.
Abu Dharr reported God’s messenger as saying, “The best things with which grey hairs are changed are henna and katam (leaves of the salam tree (mimosa flava). This dye applied with henna to the hair is said to preserve its original colour. Katam is also said to lighten the colour of the hair).
Tirmidhi, Abu Dawud and Nasa’i transmitted it.
