Abu Sufyan said: "Abu Ayyub Al-Ansari, Jabir bin 'Abdullah, and Anas bin Malik told me that when this Verse: "In it (the mosque) are men who love to clean and to purify themselves. And Allah loves those who make themselves clean and pure." was revealed, the Messenger of Allah said: “O Ansar! Allah has praised you for your cleanliness. What is the nature of your cleanliness?' They said: “We perform ablution for prayer and we take bath to cleanse ourselves of impurity due to sexual activity, and we clean ourselves with water (after urinating). He said: “This is what it is. So adhere to it”””"
