\n\n \nYahya related to me from Malik from Hisham ibn Urwa from his\nfather that Umar ibn al-Khattab wrote to Abu Musa al-Ashari that he\nshould pray asr when the sun was still pure white so that a man could\nride three farsakhs (before maghrib) and that he should pray Isha\nduring the first third of the night, or, if he delayed it, then up\nuntil the middle of the night, and he warned him not to be forgetful.\n\n

\nوَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ عُمَرَ بْنَ الْخَطَّابِ، كَتَبَ إِلَى أَبِي مُوسَى الأَشْعَرِيِّ أَنْ صَلِّ الْعَصْرَ، وَالشَّمْسُ، بَيْضَاءُ نَقِيَّةٌ قَدْرَ مَا يَسِيرُ الرَّاكِبُ ثَلاَثَةَ فَرَاسِخَ وَأَنْ صَلِّ الْعِشَاءَ مَا بَيْنَكَ وَبَيْنَ ثُلُثِ اللَّيْلِ فَإِنْ أَخَّرْتَ فَإِلَى شَطْرِ اللَّيْلِ وَلاَ تَكُنْ مِنَ الْغَافِلِينَ ‏.‏
