We used to perform the Maghrib prayer with the Prophet (may Allah's peace and blessings be upon him) and when one of us left he could still see where his arrow landed
Authentic hadithعن رافع بن خَديج الأنصاري الأوسي رضي الله عنه قال: كنا نصلي المغرب مع النبي صلى الله عليه وسلم ، فينصرف أحدنا وإنه لَيُبْصِرُ مَوَاقِعَ نَبْلِهِ.
Rāfi‘ ibn Khadīj al-Anṣāri al-Awsi (may Allah be pleased with him) reported: We used to pray the Maghrib prayer with the Prophet (may Allah's peace and blessings be upon him) and when one of us left he could still see where his arrow landed.
Explanation
This Hadīth clarifies that the Prophet (may Allah's peace and blessings be upon him) would often perform the Maghrib prayer at the beginning of its time period and clarifies that this is a part of the Sunnah. Evidence for this is that they would finish the prayer while there was still light enough for them to see where the arrows that they had shot landed.
