Abu al-Darda' reported the Messenger of Allah ﷺ as saying:
There are five thing, if anyone observe them with faith, he will enter Paradise. He who prays the five times prayer regularly, with the ablution for them, with their bowing, with their prostration and their (right) times ; keeps fast during Ramadan ; performs Hajj (pilgrimage) to the House (Ka'bah), provided he has the ability for its passage; pays Zakat happily ; and fulfills the trust (he will enter Paradise). People said: Abu al-Darda', what is fulfilling the trust ? He replied: Washing because of sexual defilement.
