Sunan at-Tirmidhi (Jami-al-Tirmidhi), Chapter: Taharah (Purification)

said, "I was much worried because of mazi and had to bath again and again. So, I asked Allah’s Messenger (SAW) about it. He said, 'It is enough to make ablution with it.' And I asked what should be done if it drops on the garment. He said that I should sprinkle a handful of water where it had stained the clothes." [Ahmed15973, Abu Dawud 210, Ibn e Majah 506]
