The Desirability of Prostrating out of Gratitude

Imam Al-Nawawi’s Riyad-us-Saliheen
Chapter 211
The Desirability of Prostrating out of Gratitude

1159. Sa`d bin Abu Waqqas (May Allah be pleased with him) reported: We left Makkah with the Messenger of Allah (sallallaahu ’alayhi wa sallam) for Al-Madinah, and when we were near `Azwara,’ he (sallallaahu ’alayhi wa sallam) alighted (from his riding-camel) raised his hands in supplication to Allah for a while and prostrated himself. He remained for a long time in prostration. Then he stood up and raised his hands for a while, after which he prostrated himself (again), and remained for a long time in prostration. Then he stood up and raised his hands for a while, after which he prostrated himself for the third time. Then he (sallallaahu ’alayhi wa sallam) said, “I supplicated my Rubb and made intercession for my Ummah, and He granted me one-third of them. So I again prostrated myself in gratitude to my Rubb. Then I raised my head and supplicated my Rubb for my Ummah, and He granted me another third of them. Again I raised my head and supplicated my Rubb for my Ummah and He granted me the last third of them. So I fell into prostration out of gratitude before my Rubb.”
