عنْ أَبِي عَبْدِاللهِ(ع) قَالَ إِنَّ اللهَ لَيَدْفَعُ بِمَنْ يُصَلِّي مِنْ شِيعَتِنَا، عَمَّنْ لا يُصَلِّي مِنْ شِيعَتِنَا وَلَوْ أَجْمَعُوا عَلَى تَرْكِ الصَّلاةِ لَهَلَكُوا.
Imam Sadiq (AS) said: Indeed, God removes evil from those Shiites who do not say prayer because of one of our Shiites among them who prays,, and if everyone tries to leave the prayer, they will surely perish.
