Riyad as-Salihin — Hadith #46413

On the authority of Ka'b bin Ujrah, may God be pleased with him, on the authority of the Messenger of God, may God bless him and grant him peace, he said: “There are things that do not disappoint the one who says them - or the one who does them - after every prescribed prayer: thirty-three tasbihahs, thirty-three tahmidas, and thirty-four takbirs” ((Narrated by Muslim)).
