6ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ بَعْضِ أَصْحَابِهِ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ دَاوُدَ بْنِ زُرْبِيٍّ عَنْ أَبِي عَبْدِ الله (عَلَيهِ السَّلام) قَالَ تَضَعُ يَدَكَ عَلَى الْمَوْضِعِ الَّذِي فِيهِ الْوَجَعُ وَتَقُولُ ثَلاثَ مَرَّاتٍ الله الله رَبِّي حَقّاً لا أُشْرِكُ بِهِ شَيْئاً اللهمَّ أَنْتَ لَهَا وَلِكُلِّ عَظِيمَةٍ فَفَرِّجْهَا عَنِّي.
6. Muhammad ibn Yahya has narrated from certain individuals of his people from Muhammad ibn ‘Isa from Dawud ibn Razin from Abu ‘Abdillah (a.s.) who has said the following: “Place your hand over the painful part and say three times: Allah, Allah, my Lord in all truth, I do not believe in anything as His partner, O Lord, You are (the help) for this and all the great troubles, provide me relief from this pain.’”
