حَدَّثَنَا عَلِيُّ بْنُ سَهْلٍ الرَّمْلِيُّ، حَدَّثَنَا الْوَلِيدُ، عَنِ ابْنِ جَابِرٍ، وَسَعِيدِ بْنِ عَبْدِ الْعَزِيزِ، وَعَبْدِ اللَّهِ بْنِ الْعَلاَءِ، عَنْ مَكْحُولٍ، عَنْ عُبَادَةَ، نَحْوَ حَدِيثِ الرَّبِيعِ بْنِ سُلَيْمَانَ قَالُوا فَكَانَ مَكْحُولٌ يَقْرَأُ فِي الْمَغْرِبِ وَالْعِشَاءِ وَالصُّبْحِ بِفَاتِحَةِ الْكِتَابِ فِي كُلِّ رَكْعَةٍ سِرًّا ‏.‏ قَالَ مَكْحُولٌ اقْرَأْ بِهَا فِيمَا جَهَرَ بِهِ الإِمَامُ إِذَا قَرَأَ بِفَاتِحَةِ الْكِتَابِ وَسَكَتَ سِرًّا فَإِنْ لَمْ يَسْكُتِ اقْرَأْ بِهَا قَبْلَهُ وَمَعَهُ وَبَعْدَهُ لاَ تَتْرُكْهَا عَلَى حَالٍ

The above mentioned tradition has been transmitted through a different chain of narrators by 'Ubadah b. al-samit like the version of al-Rabi’b Sulaiman. This version adds

Makhul used to recite the Opening of the Book (Surat al-Fatihah) silently in every rak'ah of Maghrib, 'Isha', and Fajr. Makhul said: Recite it quietly when the imam recites aloud and observes a period of silence; but if he does not observe a period of silence, recite it before him, along with him, and after him, and do not abandon it under any circumstances.
