Arabic (Original)
حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عَدِيٍّ عَنْ سَعِيدٍ عَنْ قَتَادَةَ عَنْ أَبِي الْأَحْوَصِ عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ أَنَّ نَبِيَّ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ صَلَاةُ الْجَمِيعِ تَفْضُلُ عَلَى صَلَاةِ الرَّجُلِ وَحْدَهُ خَمْسَةً وَعِشْرِينَ ضِعْفًا كُلُّهَا مِثْلُ صَلَاتِهِ.
English Translation
Muhammad ibn Abi Adi told us, from Sa'id, from Qatadah, from Abu al-Ahwas, from Abdullah ibn Mas'ud, that the Prophet of Allah, peace and blessings be upon him, said: "The prayer in congregation exceeds the prayer of a man alone by twenty-five times, each one equal to his own prayer."
