Muhammad reported from his father, Umar, on the authority of his grandfather, Ali ibn AbuTalib: When Ali travelled, he continued to travel till it became nearly dark. He then alighted and offered the sunset prayer. Then he would call for his dinner and eat it. Then he prayed the night prayer and then moved off. He would say: This is how the Messenger of Allah ﷺ used to do. Usamah ibn Zayd reported from Hafs ibn Ubaydullah, the son of Anas ibn Malik: Anas would combine them (the evening and night prayer) when the twilight disappeared. He said: The Prophet ﷺ used to do so. Az-Zuhri also reported similarly on the authority of Anas from the Prophet ﷺ.  

أَنَّ عَلِيًّا ؓ كَانَ إِذَا سَافَرَ سَارَ بَعْدَ مَا تَغْرُبُ الشَّمْسُ حَتَّى تَكَادَ أَنْ تُظْلِمَ ثُمَّ يَنْزِلُ فَيُصَلِّي الْمَغْرِبَ ثُمَّ يَدْعُو بِعَشَائِهِ فَيَتَعَشَّى ثُمَّ يُصَلِّي الْعِشَاءَ ثُمَّ يَرْتَحِلُ وَيَقُولُ هَكَذَا كَانَ رَسُولُ اللَّهِ ﷺ يَصْنَعُ قَالَ عُثْمَانُ عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عُمَرَ بْنِ عَلِيٍّ سَمِعْتُ أَبَا دَاوُدَ يَقُولُ وَرَوَى أُسَامَةُ بْنُ زَيْدٍ عَنْ حَفْصِ بْنِ عُبَيْدِ اللَّهِ يَعْنِي ابْنَ أَنَسِ بْنِ مَالِكٍ أَنَّ أَنَسًا كَانَ يَجْمَعُ بَيْنَهُمَا حِينَ يَغِيبُ الشَّفَقُ وَيَقُولُ كَانَ النَّبِيُّ ﷺ يَصْنَعُ ذَلِكَ وَرِوَايَةُ الزُّهْرِيِّ عَنْ أَنَسٍ عَنِ النَّبِيِّ ﷺ مِثْلُهُ
