Sahih al-Bukhari 559
Sahih al-Bukhari · Book 9: Times of the Prayers · The time of the Maghrib prayer (evening prayer)
Narrated Rafi` bin Khadij:
حَدَّثَنَا مُحَمَّدُ بْنُ مِهْرَانَ ، قَالَ حَدَّثَنَا الْوَلِيدُ ، قَالَ حَدَّثَنَا الأَوْزَاعِيُّ ، قَالَ حَدَّثَنَا أَبُو النَّجَاشِيِّ، صُهَيْبٌ مَوْلَى رَافِعِ بْنِ خَدِيجٍ قَالَ سَمِعْتُ رَافِعَ بْنَ خَدِيجٍ ، يَقُولُ كُنَّا نُصَلِّي الْمَغْرِبَ مَعَ النَّبِيِّ صلى الله عليه وسلم فَيَنْصَرِفُ أَحَدُنَا وَإِنَّهُ لَيُبْصِرُ مَوَاقِعَ نَبْلِهِ.
We used to offer the Maghrib prayer with the Prophet (ﷺ) and after finishing the prayer one of us may go away and could still see as Par as the spots where one's arrow might reach when shot by a bow.
