Man La Yahduruhu al-Faqih narrates from Maymun b. Mihran, 'I was once sitting in the presence of al-Hasan b. ?Ali (AS) when a man came to him, saying, ?O son of the Prophet of Allah, verily x is claiming money from me that I owe him and he wants to arrest me.' So he replied, 'By Allah, I do not have money to pay your debt on your behalf.' So he asked, 'Then talk to him.' So he (AS) put on his sandals, whereupon I asked him, ?O son of the Prophet of Allah, have you forgotten the fact that you are in a state of retreat?' So he replied, 'No, I have not forgotten, but I have heard my father (AS) narrating from the authority of [my grandfather], the Prophet of Allah (SAWA) that he had said, 'He who strives to fulfil a fellow Muslim brother's need is as if he has worshipped Allah, Mighty and Exalted, for nine thousand years, fasting during the day and standing in prayer at night.'
