" On the second day he (the Holy Prophet) observed the evening prayer before the disappearance of the twilight."  

مسلم:٦١٤bحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا وَكِيعٌ عَنْ بَدْرِ بْنِ عُثْمَانَ عَنْ أَبِي بَكْرِ بْنِ أَبِي مُوسَى سَمِعَهُ مِنْهُ عَنْ أَبِيهِ

أَنَّ سَائِلاً أَتَى النَّبِيَّ ﷺ فَسَأَلَهُ عَنْ مَوَاقِيتِ الصَّلاَةِ بِمِثْلِ حَدِيثِ ابْنِ نُمَيْرٍ غَيْرَ أَنَّهُ قَالَ فَصَلَّى الْمَغْرِبَ قَبْلَ أَنْ يَغِيبَ الشَّفَقُ فِي الْيَوْمِ الثَّانِي
