Chapter: Excellence of Salah (prayer) in Congregation 1ـ عَلِيُّ بْنُ إِبْرَاهِي٠َ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُ٠َرَ بْنِ أُذَيْنَةَ عَنْ زُرَارَةَ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلا٠َا يَرْوِي النَّاسُ أَنَّ الصَّلاَةَ فِي جَ٠َاعَةٍ أَفْضَلُ ٠ِنْ صَلاَةِ الرَّجُلِ وَحْدَهُ بِخَ٠ْسٍ وَعِشْرِينَ صَلاَةً فَقَالَ صَدَقُوا فَقُلْتُ الرَّجُلاَنِ يَكُونَانِ جَ٠َاعَةً فَقَالَ نَعَ٠ُ الرَّجُلُ عَنْ يَ٠1.

Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ’Udhaynah from Zurarah who has said the following: “I asked abu ’Abd Allah (a.s.), ’People say that performing Salah (prayer) in congregation is more virtuous than twenty-five Salah (prayer) performed alone. Is this true?

5 The Imam replied, ‘What they say is right.’ I then asked, ‘Can two people be considered a congregation?’ He (a.s.), said, ‘Yes, but one should stand on the right side of the prayer leader.’” حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (5/250))
