It is narrated from Hazrat Ya'la (may Allah be pleased with him) that when the Prophet (peace and blessings be upon him) would stand for prayer, before the takbeer he would wipe his hand over the faces of his companions. I had applied a perfume called khuluq, so the Prophet (peace and blessings be upon him) wiped his hand over the faces of the other companions but left me out. I went back and washed it off, and when I attended the next prayer, the Prophet (peace and blessings be upon him) wiped his hand over my face and said, "You have returned with a good religion." 'Ala (Ya'la) repented, and his voice reached the sky.
