Musannaf Ibn Abi Shayba 28:379

Waki’ narrated to us, he said: Rabi’ ibn Hassan narrated to us, from his mother, who said: Ali used to distribute *wars* (a yellow dye) and saffron among us. She said: Ali entered the room one time and saw some grains scattered, so he began to pick them up and say: "You have become satiated, O family of Ali."
