عَن عَوْف بن مَالك قَالَ: قُمْتُ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَلَمَّا رَكَعَ مَكَثَ قَدْرَ سُورَةِ الْبَقَرَةِ وَيَقُولُ فِي رُكُوعِهِ: «سُبْحَانَ ذِي الْجَبَرُوتِ والملكوت والكبرياء وَالْعَظَمَة» . رَوَاهُ النَّسَائِيّ

Ibn Jubair said that he heard Anas b. Malik declare, “After the death of God’s Messenger I never prayed behind anyone whose prayer more closely resembled that of God’s Messenger than this young man,” meaning ‘Umar b. ‘Abd al-‘AzIz.* He reported him as saying, “I computed that he uttered ten tasbihas when bowing and ten when prostrating himself.” * He was Caliph from 99 to 101 A.H. and was noted for his piety.Abu Dawud and Nasa’i transmitted it.
