On Friday, do not climb over people's necks to reach the front. The Prophet ﷺ said to a man doing so during the khuṭbah: “Sit down, for you have caused harm.” (Abū Dāwūd — ṣaḥīḥ). Come early instead, and fill the front rows first.
العربية: عن عبد الله بن بُسر رضي الله عنه قال: جاء رجلٌ يتخطّى رقاب الناس يوم الجمعة والنبيّ ﷺ يخطب، فقال له النبيّ ﷺ: «اجلِس فقد آذيت». (أبو داود).
Arrive early to Jumuʿah and sit where you can — do not climb over the worshippers.
