Ibn ‘Abbas said that God’s Messenger stood in humble supplication daily for a month at the noon, afternoon; sunset, evening and morning prayer when he said, “God listens to him who praises Him” in the last rak'a, invoking a curse on some clans of the B. Sulaim, Ri‘l, Dhakwan and ‘Usayya, and those standing behind him said Amen.
Abu Dawud transmitted it.
