Mishkat al-Masabih #343

Abu Ayyub, Jabir and Anas said that when this verse came down, “In it are men who love to be purified, and God loves those who purify themselves,”* God’s messenger said, “God has praised you Ansar for purification. What does your purification consist of?” They replied, “We perform ablution for prayer, wash after seminal emission, and cleanse ourselves with water.” He said, “That is it, so keep on doing it.” *1. Qur'an, ix, 108. Ibn Majah transmitted it.
