We used to pray Maghrib with the Prophet ﷺ, and one of us would leave afterward still able to see where his arrows landed.
كنا نصلي المغرب مع النبي ﷺ فينصرف أحدنا، وإنه ليبصر مواقع نبله.
Bukhari narrated it in the Book of Prayer Times (559), and Muslim in the Book of Mosques (637), both from Muhammad bin Mihran, who said, Walid bin Muslim narrated to us, who said, Uzai narrated to us, who said, Abu Najashi, that is Ataa bin Suhayb, the freed slave of Rafi bin Khadij, narrated to me, saying, "I heard Rafi bin Khadij," and then he related the hadith. Their wording is identical and their teacher is the same.His statement, "so that one could see where his arrow fell," means that he would pray it early, right at the start of its time, as soon as the sun set, so that by the time we finished, one of us could shoot an arrow from his bow and still see where it landed because of the remaining light.These two hadiths indicate that Maghrib is to be prayed promptly right after sunset, and this is a matter of consensus. As for the hadiths about delaying Maghrib until near the disappearance of twilight, these were meant to show that delaying it is permissible, since they were given in answer to someone asking about the time. This is what Nawawi noted.
