[Machine] Ubayy ibn Ka'b prayed the Fajr prayer with us, the Messenger of Allah ﷺ. When he finished the prayer, he noticed that there were only a few people in the mosque, so he asked, "Is so-and-so present?" We replied, "Yes," until he counted three individuals. He then said, "Indeed, it is not a heavier prayer for the hypocrites than the prayer of Al-Isha and the Fajr prayer in the Hereafter." And he mentioned the Hadith in its entirety.  

أُبَيٌّ صَلَّى بِنَا رَسُولُ اللهِ ﷺ صَلَاةَ الْفَجْرِ فَلَمَّا قَضَى الصَّلَاةَ رَأَى مِنْ أَهْلِ الْمَسْجِدِ قِلَّةً فَقَالَ شَاهِدٌ فُلَانٌ؟ قُلْنَا نَعَمْ حَتَّى عَدَّ ثَلَاثَةَ نَفَرٍ فَقَالَ إِنَّهُ لَيْسَ مِنْ صَلَاةٍ أَثْقَلُ عَلَى الْمُنَافِقِينَ مِنْ صَلَاةِ الْعِشَاءِ الْآخِرَةِ وَمِنْ صَلَاةِ الْفَجْرِ وَذَكَرَ الْحَدِيثَ بِطُولِهِ
