Jami` at-Tirmidhi 3509

Abu Hurairah narrated that the Messenger of Allah (ﷺ) said:“When you pass by the gardens of Paradise, then feast.” I said: “O Messenger of Allah, and what are the gardens of Paradise?” He said, “The Masajid.” I said: “And what is feasting, O Messenger of Allah?” He said: “‘Glory is to Allah, (Subḥān Allāh)’ and ‘All praise is due to Allah, (Al-Ḥamdulillāh)’ and ‘None has the right to be worshipped but Allah, (Lā Ilāha Illallāh)’ and ‘Allah is the Greatest (Allāhu Akbar).’”
