It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) would very rarely directly confront someone face to face if he saw them involved in something impermissible. One day, a man came and there were traces of yellow color on him. When he left, the Prophet (peace and blessings be upon him) said: "If he would change or remove that yellow (garment), it would be better."
