Musnad Ahmad 2:142

'Abd al-Razzaq narrated to us, Yunus ibn Sulaym informed me, he said: Yunus ibn Yazid al-Ayli dictated to me, from Ibn Shihab, from 'Urwah ibn al-Zubayr, from 'Abd al-Rahman ibn 'Abd al-Qari: I heard 'Umar ibn al-Khattab saying: When the revelation would descend upon the Messenger of Allah, may Allah bless him and grant him peace, a buzzing sound would be heard near his face like the buzzing of bees. We waited for a while, then he faced the Qiblah and raised his hands, and said: "O Allah, increase us and do not decrease us, honor us and do not humiliate us, give us and do not deprive us, prefer us and do not prefer others over us, and be pleased with us and satisfy us." Then he said: "Ten verses have been revealed to me; whoever upholds them will enter Paradise." Then he recited to us: {Successful are the believers} until he completed the ten verses.
