Ibn al-Qayyim رحمه الله: _"Friday prayer is one of the most important obligations in Islam, and one of the greatest gatherings of the Muslims. Gathering on Friday is more important and more obligatory than any other gathering apart from ‘Arafah. Whoever neglects it, Allāh will place a seal on his heart."_ [Zaad Al-Ma’aad | Book 3, Pg. 31-32]
