Narrated `Aisha:
حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ ، قَالَ حَدَّثَنَا اللَّيْثُ ، عَنْ عُقَيْلٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُرْوَةَ ، أَنَّ عَائِشَةَ ، أَخْبَرَتْهُ قَالَتْ، أَعْتَمَ رَسُولُ اللَّهِ صلى الله عليه وسلم لَيْلَةً بِالْعِشَاءِ، وَذَلِكَ قَبْلَ أَنْ يَفْشُوَ الإِسْلاَمُ، فَلَمْ يَخْرُجْ حَتَّى قَالَ عُمَرُ نَامَ النِّسَاءُ وَالصِّبْيَانُ. فَخَرَجَ فَقَالَ لأَهْلِ الْمَسْجِدِ " مَا يَنْتَظِرُهَا أَحَدٌ مِنْ أَهْلِ الأَرْضِ غَيْرُكُمْ " .
Allah's Messenger (ﷺ) once delayed the `Isha' prayer and that was during the days when Islam still had not spread. The Prophet (ﷺ) did not come out till `Umar informed him that the women and children had slept. Then he came out and said to the people of the mosque: "None amongst the dwellers of the earth has been waiting for it (`Isha prayer) except you."
