People used to perform istinja (cleaning after relieving oneself) with stones, and a man from the Ansar ate some food, which upset his stomach. He then performed istinja with water. Allah سبحانه وتعالى, Blessed and Exalted, revealed: "Indeed, Allah سبحانه وتعالى loves those who repent and loves those who purify themselves." (Surah Al Baqarah 2:222). The Messenger of Allah صلى الله عليه وعلى آله وسلم called him, and the man feared that something negative had been revealed about him. When he entered, the Prophet asked him, "Have you done anything today?" He replied: "Yes, O’ Messenger of Allah صلى الله عليه وعلى آله وسلم, I ate some food, which upset my stomach, so I performed istinja with water." The Prophet then said: "Rejoice! For Allah سبحانه وتعالى, Blessed and Exalted, has revealed concerning you: 'Indeed, Allah سبحانه وتعالى loves those who repent and loves those who purify themselves.' You are among the first to repent and among the first to purify themselves."
