وَمَآ ءَاتَيْنَٰهُم مِّن كُتُبٍۢ يَدْرُسُونَهَا ۖ وَمَآ أَرْسَلْنَآ إِلَيْهِمْ قَبْلَكَ مِن نَّذِيرٍۢ
And We have given them no scriptures which they study, nor sent We unto them, before thee, any warner.

Sahih al-Bukhari
Friday Prayer
Chapter: One should not separate two persons on Fridays
Narrated Salman Al-Farsi:
Allah's Messenger (ﷺ) (p.b.u.h) said, "Anyone who takes a bath on Friday and cleans himself as much as he can and puts oil (on his hair) or scents himself; and then proceeds for the prayer and does not force his way between two persons (assembled in the mosque for the Friday prayer), and prays as much as is written for him and remains quiet when the Imam delivers the Khutba, all his sins in between the present and the last Friday will be forgiven."
