Yahya related to me from Malik from Muhammad ibn Yusuf that as- Sa'ib ibn Yazid said, "Umar ibn al-Khattab ordered Ubayy ibn Kab and Tamim ad-Dari to watch the night in prayer with the people for eleven rakas.The reciterof the Qur'an would recite the Mi'in (a group of medium-sized suras) until we would be leaning on our staffs from having stood so long in prayer. And we would not leave until the approach of dawn."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ مُحَمَّدِ بْنِ يُوسُفَ، عَنِ السَّائِبِ بْنِ يَزِيدَ، أَنَّهُ قَالَ أَمَرَ عُمَرُ بْنُ الْخَطَّابِ أُبَىَّ بْنَ كَعْبٍ وَتَمِيمًا الدَّارِيَّ أَنْ يَقُومَا، لِلنَّاسِ بِإِحْدَى عَشْرَةَ رَكْعَةً قَالَ وَقَدْ كَانَ الْقَارِئُ يَقْرَأُ بِالْمِئِينَ حَتَّى كُنَّا نَعْتَمِدُ عَلَى الْعِصِيِّ مِنْ طُولِ الْقِيَامِ وَمَا كُنَّا نَنْصَرِفُ إِلاَّ فِي فُرُوعِ الْفَجْرِ .
