[Machine] Umar ibn al-Khattab gathered the people around Ubay ibn Ka'b and prayed with them for twenty nights. He did not lead them in prayer except for the remaining half. When the last ten nights came, he was absent and prayed in his house. They would say, "Ubay has stayed."
أَنَّ عُمَرَ بْنَ الْخَطَّابِ ؓ جَمَعَ النَّاسَ عَلَى أُبَيِّ بْنِ كَعْبٍ فَكَانَ يُصَلِّي بِهِمْ عِشْرِينَ لَيْلَةً وَلَا يَقْنُتُ بِهِمْ إِلَّا فِي النِّصْفِ الْبَاقِي فَإِذَا كَانَتِ الْعَشْرُ الْأَوَاخِرُ تَخَلَّفَ فَصَلَّى فِي بَيْتِهِ فَكَانُوا يَقُولُونَ أَبَقَ أُبَيٌّ
