5. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al- Hassan ibn Mahbub from Jamil ibn Salih from Dharih al-Muharibi who has said the following: “I heard Abu ‘Abdillah عليه السلام saying, ‘Any believer who relieves a believer from his hardships in a constraining condition Allah will make his (helper’s) needs easily met in this world and in the next.’ The Imam said, ‘Whoever provides cover for the private matters of a believer for which he is afraid, Allah will provide cover for his (helper’s) seventy private matters of this world and in the next life.’ The Imam said, ‘Allah supports a believer as long as he supports his believing brother (in belief). You must benefit from the good advice and be interested in good deeds.’”
