الترمذي:١٨٥ – حَدَّثَنَا هَنَّادٌ حَدَّثَنَا وَكِيعٌ عَنْ كَهْمَسِ بْنِ الْحَسَنِ عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ عَنْ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ

عَنِ النَّبِيِّ ﷺ قَالَ بَيْنَ كُلِّ أَذَانَيْنِ صَلاَةٌ لِمَنْ شَاءَ وَفِي الْبَابِ عَنْ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ  

قَالَ أَبُو عِيسَى حَدِيثُ عَبْدِ اللَّهِ بْنِ مُغَفَّلٍ حَدِيثٌ حَسَنٌ صَحِيحٌ وَقَدِ اخْتَلَفَ أَصْحَابُ النَّبِيِّ ﷺ فِي الصَّلاَةِ قَبْلَ الْمَغْرِبِ فَلَمْ يَرَ بَعْضُهُمُ الصَّلاَةَ قَبْلَ الْمَغْرِبِ وَقَدْ رُوِيَ عَنْ غَيْرِ وَاحِدٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَنَّهُمْ كَانُوا يُصَلُّونَ قَبْلَ صَلاَةِ الْمَغْرِبِ رَكْعَتَيْنِ بَيْنَ الأَذَانِ وَالإِقَامَةِ وَقَالَ أَحْمَدُ وَإِسْحَاقُ إِنْ صَلاَّهُمَا فَحَسَنٌ وَهَذَا عِنْدَهُمَا عَلَى الاِسْتِحْبَابِ
