Narrated Rafi' bin Khadij (RA):

We used to offer the Maghrib prayer with Allah's Messenger (ﷺ) and then one of us would go (out of the mosque) and be able to see the spot his would fall at. [Agreed upon].

وَعَنْ رَافِعِ بْنِ خَدِيجٍ قَالَ: { كُنَّا نُصَلِّي اَلْمَغْرِبَ مَعَ اَلنَّبِيِّ ‏- صلى الله عليه وسلم ‏-فَيَنْصَرِفُ أَحَدُنَا وَإِنَّهُ لَيُبْصِرُ مَوَاقِعَ نَبْلِهِ } مُتَّفَقٌ عَلَيْهِ [1]‏ .‏
