Mishkat al-Masabih, 611

Abu Huraira reported God’s Messenger as saying, “Were it not for causing distress to my people, I would command them to postpone the night prayer till a third or a half of the night had passed.” Ahmad, Tirmidhi and Ibn Majah transmitted it.

وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «لَوْلَا أَن أشق على أمتِي لأمرتهم أَنْ يُؤَخِّرُوا الْعِشَاءَ إِلَى ثُلُثِ اللَّيْلِ أَوْ نصفه» . رَوَاهُ أَحْمد وَالتِّرْمِذِيّ وَابْن مَاجَه
