Hadith 1155
Narrated Abu Huraira: That once Allah's Apostle (p.b.u.h) said, "Your brother, i.e. `Abdullah bin Rawaha does not say obscene (referring to his verses): Amongst us is Allah's Apostle, who recites His Book when it dawns. He showed us the guidance, after we were blind. We believe that whatever he says will come true. And he spends his nights in such a way as his sides do not touch his bed. While the pagans were deeply asleep."
Hadith 6151
Narrated Al-Haitham bin Abu Sinan: that he heard Abu Huraira in his narration, mentioning that the Prophet said, "A Muslim brother of yours who does not say dirty words." and by that he meant Ibn Rawaha, "said (in verse): 'We have Allah's Apostle with us who recites the Holy Qur'an in the early morning time. He gave us guidance and light while we were blind and astray, so our hearts are sure that whatever he says, will certainly happen. He does not touch his bed at night, being busy in worshipping Allah while the pagans are sound asleep in their beds.' "
