Mishkat al-Masabih 2494
‘Umar b. al-Khattab said:
When the inspiration was sent down to the Prophet, a low sound was heard near his face like the humming of bees. One day when inspiration was sent down to him and we had waited for a time, it left him, then facing the qibla and raising his hands, he said, “O God, give us more and do not give us less; honour us and do not humiliate us; give us and do not withhold from us; choose us and do not prefer others to us; please us and be pleased with us.” He then said, “I have had sent down to me ten verses which will provide entrance to paradise for those who recite them.” He then recited, “The believers have been successful” and continued till he had completed ten verses, 1 
1. Qur'an, xxiii, 1-10.

Ahmad and Tirmidhi transmitted it.
وَعَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا أُنْزِلَ عَلَيْهِ الْوَحْيُ سُمِعَ عِنْدَ وَجْهِهِ دوِي كَدَوِيِّ النَّحْل فأنل عَلَيْهِ يَوْمًا فَمَكَثْنَا سَاعَةً فَسُرِّيَ عَنْهُ فَاسْتَقْبَلَ الْقِبْلَةَ وَرَفَعَ يَدَيْهِ وَقَالَ: «اللَّهُمَّ زِدْنَا وَلَا تَنْقُصْنَا وَأَكْرِمْنَا وَلَا تُهِنَّا وَأَعْطِنَا وَلَا تَحْرِمْنَا وَآثِرْنَا وَلَا تُؤْثِرْ عَلَيْنَا وَأَرْضِنَا وَارْضَ عَنَّا» . ثُمَّ قَالَ: «أُنْزِلَ عَلَيَّ عَشْرُ آيَاتٍ مَنْ أَقَامَهُنَّ دَخَلَ الْجَنَّةَ» ثُمَّ قَرَأَ: (قَدْ أَفْلَحَ الْمُؤْمِنُونَ)
حَتَّى خَتَمَ عَشْرَ آيَاتٍ. رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيّ
