Ya‘la b. Murra told that when the Prophet saw some khaluq (A liquid, yellow perfume mainly composed of saffron) on him he asked whether he had a wife, and when he replied that he had not he said, “Wash it, then wash it, then wash it, and do not use it again.”
Tirmidhi and Nasa'i transmitted it.
I came to my family after a journey with my hands chapped and they perfumed me with saffron. In the morning I went to the Prophet and gave him a greeting, but instead of responding to it he said, “Go away and wash this off yourself.”
Abu Dawud transimitted it.
‘Amr b. Shu'aib; on his father's authority, said his grandfather told that the Prophet used to take something off the side and the bottom of his beard.
Tirmidhi transmitted it, saying this is a gharib tradition.
