The time of `Isha and delaying it
وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا ابْنُ جُرَيْجٍ، أَخْبَرَنِي نَافِعٌ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم شُغِلَ عَنْهَا لَيْلَةً فَأَخَّرَهَا حَتَّى رَقَدْنَا فِي الْمَسْجِدِ ثُمَّ اسْتَيْقَظْنَا ثُمَّ رَقَدْنَا ثُمَّ اسْتَيْقَظْنَا ثُمَّ خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم ثُمَّ قَالَ " لَيْسَ أَحَدٌ مِنْ أَهْلِ الأَرْضِ اللَّيْلَةَ يَنْتَظِرُ الصَّلاَةَ غَيْرُكُمْ " .
Abdullah b. 'Umar reported that the Messenger of Allah (ﷺ) was one night occupied (in some work) and he delayed it ('Isya' prayer) till we went to sleep in the mosque. We then woke up and again went to sleep and again woke up. The Messenger of Allah (ﷺ) then came to us and said: None among the people of the earth except you waits for prayer in the night.
