Musannaf Ibn Abi Shaybah 37777 — The reward of glorifying and praising

It is narrated from Sa'id bin al-Musayyib that he said: We were with Sayyiduna Sa'd bin Malik (may Allah be pleased with him), and he remained silent for a moment and then said: "Indeed, in this silence of mine I have obtained what the Nile and the Euphrates irrigate." The narrator said: We said: "What have you obtained?" He said: "'Subhan Allah, wal-hamdu lillah, wa la ilaha illa Allah, wa Allahu Akbar' (Glory be to Allah, all praise is for Allah, there is no god but Allah, and Allah is the Greatest)."
