4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنِ ابْنِ مَحْبُوبٍ عَنْ أَبِي الْعَبَّاسِ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) فِي الْمُبَاهَلَةِ قَالَ تُشَبِّكُ أَصَابِعَكَ فِي أَصَابِعِهِ ثُمَّ تَقُولُ اللهمَّ إِنْ كَانَ فُلانٌ جَحَدَ حَقّاً وَأَقَرَّ بِبَاطِلٍ فَأَصِبْهُ بِحُسْبَانٍ مِنَ السَّمَاءِ أَوْ بِعَذَابٍ مِنْ عِنْدِكَ وَتُلاعِنُهُ سَبْعِينَ مَرَّةً.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ibn Mahbub from abu al-‘ Abbas from Abu ‘Abdillah (a.s.) who has said the following about al-Mubahalah: “Crisscross the fingers of your hand with his fingers and say, ‘O Lord, if so and so has rejected a truth or has professed a falsehood, make him suffer a misfortune from the sky or a punishment from You’, and then renounce each other seventy times.’”
