عَنْ سَعِيدِ بْنِ جُبَيْرٍ عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ: مَا رَأَيْتُ أَحَدًا أَشْبَهَ صَلَاةً بِرَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مِنْ هَٰذَا الْغُلَامِ يَعْنِي عُمَرَ بْنَ عَبْدِ الْعَزِيزِ، قَالَ: فَحَزَرْنَا فِي الرُّكُوعِ عَشْرَ تَسْبِيحَاتٍ وَفِي السُّجُودِ عَشْرَ تَسْبِيحَاتٍ
It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him), he says: I have not seen anyone who resembled the Messenger of Allah (peace and blessings be upon him) more in prayer than this young man (i.e., Umar bin Abdul Aziz). Saeed bin Jubair says: We estimated that this young man recited the tasbihat ten times each in his bowing and prostration.
