1ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى رَفَعَهُ عَنْ حَرِيزٍ عَنْ يَعْقُوبَ الْقُمِّيِّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ ثَمَنُ الْجَنَّةِ لا إِلَهَ إِلا الله وَالله أَكْبَرُ.
1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa in a marfu ’ manner from Hariz from Ya’qub al-Qummi from Abu ‘Abdillah (a.s.) who has said the following: “The cost of paradise is (sincerely) saying: ‘No one deserves to be worshipped except Allah and Allah is greater than everyones’ description.’”
