مسلم:٦٣٧b – وَحَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ أَخْبَرَنَا شُعَيْبُ بْنُ إِسْحَاقَ الدِّمَشْقِيُّ حَدَّثَنَا الأَوْزَاعِيُّ حَدَّثَنِي أَبُو النَّجَاشِيِّ حَدَّثَنِي رَافِعُ بْنُ خَدِيجٍ قَالَ

كُنَّا نُصَلِّي الْمَغْرِبَ بِنَحْوِهِ  

abudawud:417 – ʿAmr b. ʿAlī > Ṣafwān b. ʿĪsá > Yazīd b. Abū ʿUbayd > Salamah b. al-Akwaʿ

The Prophet ﷺ used to say the Maghrib prayer immediately after the sun had set when its upper side would disappear.  

أبو داود:٤١٧ – حَدَّثَنَا عَمْرُو بْنُ عَلِيٍّ عَنْ صَفْوَانَ بْنِ عِيسَى عَنْ يَزِيدَ بْنِ أَبِي عُبَيْدٍ عَنْ سَلَمَةَ بْنِ الأَكْوَعِ قَالَ

كَانَ النَّبِيُّ ﷺ يُصَلِّي الْمَغْرِبَ سَاعَةَ تَغْرُبُ الشَّمْسُ إِذَا غَابَ حَاجِبُهَا
