قَدْ خَسِرَ ٱلَّذِينَ كَذَّبُوا۟ بِلِقَآءِ ٱللَّهِ ۖ حَتَّىٰٓ إِذَا جَآءَتْهُمُ ٱلسَّاعَةُ بَغْتَةًۭ قَالُوا۟ يَٰحَسْرَتَنَا عَلَىٰ مَا فَرَّطْنَا فِيهَا وَهُمْ يَحْمِلُونَ أَوْزَارَهُمْ عَلَىٰ ظُهُورِهِمْ ۚ أَلَا سَآءَ مَا يَزِرُونَ
They indeed are losers who deny their meeting with Allah until, when the Hour cometh on them suddenly, they cry: Alas for us, that we neglected it! They bear upon their backs their burdens. Ah, evil is that which they bear!

Chapter: The religious gathering in circles and sitting in the mosque
Narrated Nafi`:
Ibn `Umar said, "While the Prophet (ﷺ) was on the pulpit, a man asked him how to offer the night prayers. He replied, 'Pray two rak`at at a time and then two and then two and so on, and if you are afraid of the dawn (the approach of the time of the Fajr prayer) pray one rak`a and that will be the witr for all the rak`at which you have offered." Ibn `Umar said, "The last rak`at of the night prayer should be odd, for the Prophet (ﷺ) ordered it to be so.
