لَا يُقِيمُ الرَّجُلُ الرَّجُلَ مِنْ مَقْعَدِهِ ثُمَّ يَجْلِسُ فِيهِ وَلَكِنْ تَفَسَّحُوا وَتَوَسَّعُوا

لَا يَغْتَسِلُ رَجُلٌ يَوْمَ الْجُمُعَةِ وَيَتَطَهَّرُ مَا اسْتَطَاعَ مِنْ طُهْرٍ وَيَدَّهِنُ مِنْ دُهْنِهِ أَوْ يَمَسُّ مِنْ طِيبِ بَيْتِهِ ثُمَّ يَخْرُجُ فَلَا يُفَرِّقُ بَيْنَ اثْنَيْنِ ثُمَّ يُصَلِّي مَا كُتِبَ لَهُ ثُمَّ يُنْصِتُ إِذَا تَكَلَّمَ الْإِمَامُ إِلَّا غُفِرَ لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الْأُخْرَى
No one takes a bath on Friday, purifies himself as much as he can, uses oil or perfume in his house, then proceeds for prayer, and he does not separate two persons sitting together, then prays as much as is written for him, and remains silent while the prayer leader is delivering the sermon, except that his sins between this Friday and the previous would be forgiven.

O Allah, apportion for us such fear of you that will protect us from acts of disobedience, and apportion for us obedience to you that will take us to Paradise, and apportion for us certainty that will make calamities easier to endure. O Allah, let us enjoy our hearing, our sight, and our power as long as you keep us alive and make heirs for us from our offspring and let retaliation be upon those who oppress us. Support us against those who are hostile to us and let no misfortune afflict our religion. Let not the world be our greatest concern or the limit of our knowledge, and let not those rule over us who are not merciful to us.
