Musannaf Ibn Abi Shaybah 37797 — Reports on the virtue of remembering

It is narrated from Suwayd bin Juhayl that he said: Whoever says after Asr: 'La ilaha illallah, lahul-mulku wa lahul-hamdu wa huwa ala kulli shay'in qadir' (None has the right to be worshipped except Allah; His is the dominion and His is the praise, and He has power over all things), these words will keep contending on behalf of the one who said them until tomorrow.
