2. Ṣalāh (Ritual Prayer)
٢۔ كتاب الصلاة
When you tell (your brother on Friday) to be silent while the imam is giving the sermon you are guilty of idle talk.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا قُلْتَ أَنْصِتْ وَالإِمَامُ يَخْطُبُ فَقَدْ لَغَوْتَ
The Prophet ﷺ said: Three types of people attend Friday prayer; One is present in a frivolous way and that is all he gets from it; another comes with a supplication, Allah may grant or refuse his request as He wishes; another is present silently and quietly with-out stepping over a Muslim or annoying anyone, and that is an atonement for his sins till the next Friday and three days more, the reason being that Allah, the Exalted, says: "He who does a good deed will have ten times as much" (vi.160).
عَنِ النَّبِيِّ ﷺ قَالَ يَحْضُرُ الْجُمُعَةَ ثَلاَثَةُ نَفَرٍ رَجُلٌ حَضَرَهَا يَلْغُو وَهُوَ حَظُّهُ مِنْهَا وَرَجُلٌ حَضَرَهَا يَدْعُو فَهُوَ رَجُلٌ دَعَا اللَّهَ ﷻ إِنْ شَاءَ أَعْطَاهُ وَإِنْ شَاءَ مَنَعَهُ وَرَجُلٌ حَضَرَهَا بِإِنْصَاتٍ وَسُكُوتٍ وَلَمْ يَتَخَطَّ رَقَبَةَ مُسْلِمٍ وَلَمْ يُؤْذِ أَحَدًا فَهِيَ كَفَّارَةٌ إِلَى الْجُمُعَةِ الَّتِي تَلِيهَا وَزِيَادَةُ ثَلاَثَةِ أَيَّامٍ وَذَلِكَ بِأَنَّ اللَّهَ ﷻ يَقُولُ { مَنْ جَاءَ بِالْحَسَنَةِ فَلَهُ عَشْرُ أَمْثَالِهَا }
