Sahih Muslim Book - 5, Hadith - 1434

وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ الْفَزَارِىُّ أَخْبَرَنَا إِسْمَاعِيلُ بْنُ أَبِى خَالِدٍ حَدَّثَنَا قَيْسُ بْنُ أَبِى حَازِمٍ قَالَ سَمِعْتُ جَرِيرَ بْنَ عَبْدِ اللَّهِ وَهُوَ يَقُولُ كُنَّا جُلُوسًا عِنْدَ رَسُولِ اللَّهِ -صلى الله عليه وسلم- إِذْ نَظَرَ إِلَى الْقَمَرِ لَيْلَةَ الْبَدْرِ فَقَالَ « أَمَا إِنَّكُمْ سَتَرَوْنَ رَبَّكُمْ كَمَا تَرَوْنَ هَذَا الْقَمَرَ لاَ تُضَامُّونَ فِى رُؤْيَتِهِ فَإِنِ اسْتَطَعْتُمْ أَنْ لاَ تُغْلَبُوا عَلَى صَلاَةٍ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا ». يَعْنِى الْعَصْرَ وَالْفَجْرَ ثُمَّ قَرَأَ جَرِيرٌ (وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ غُرُوبِهَا ).

Qais bin Abi Hazim said: "I heard Jarir bin 'Abdullah say: 'We were sitting with the Messenger of Allah (s.a.w) when he looked at the moon while it was full, and he said: "You will see your Lord as you are seeing this moon, and you will not crowd one another in order to see Him. If you can, do not let yourselves be distracted from praying before the sun rises and before it sets," meaning Fajr and 'Asr. Then Jarir recited: "And glorify the praises of your Lord before the rising of the sun, and before its setting."
