1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn ‘Isa from ‘Abd al-Rahman ibn abu Najran and ibn Faddal from certain individuals of our people from Abu ‘Abdillah (a.s.) who has said the following: “For an ailment the Imam (a.s.) would say, ‘O Lord, You have criticized certain nations saying, “(Muhammad), tell them, ‘Seek help from those whom you consider equal to Allah. They are not able to remove or change your hardships’” (17:56) O the One besides whom no one is able to provide me relief or divert the hardships away from me, confer al-Salat (favors) upon Muhammad and his family, grant me relief and divert the suffering from me to those who worship things other than You.’”

2. Ahmad ibn Muhammad has narrated from ‘Abd al-‘Aziz ibn al-Muhtadi from Yunus ibn ‘Abd al-Rahman from Dawud ibn Razin who has said the following: “I fell severely ill in Madiana and Abu ‘Abdillah (a.s.) had found out about it. He wrote to me, ‘Your ailment has come to our notice and you should buy one Sa’a (about 3 kg) of wheat, lie down on your back, pour it on your chest, as is done and say, “O Lord, I plead before You through Your name with which when a helpless person pleads before You, You remove his hardship, establish him on earth, and appoint him as Your deputy among Your creatures, bestow al-Salat (favors) upon Muhammad and his family, grant me good health and recovery from my ailment.” Then sit straight, collect the wheat around you and say what you just said and distribute it among the destitute a handful for each one and say what you just said (above supplication).’ “Dawud has said, ‘I followed his instruction and it was like I was freed from a rope with which I was tied up. Many people tried it and benefited thereby.’”
