“Once, during the month of Ramadan, Sadir went to visit abu ‘Abd Allah (a.s.). The Imam asked, ‘O Sadir, do you know which nights are these days?’ He replied, ‘Yes, I pray to Allah to keep my soul and the soul of my father in service for your cause, these are the nights of the month of Ramadan, but what do they signify?’ The Imam then said, ‘Can you set free ten slaves from the descendants of Isma‘il in every one of these nights?’ Sadir replied, ‘I pray to Allah to keep the souls of my parents in service for your cause, my belongings are not that much.’ The Imam then reduced the number of slaves until it was only one slave, but he kept saying, ‘My belongings are not enough.’ The Imam then asked, ‘Can you serve food to a Muslim every night.’ He replied, ‘Yes, I can do so. I can even serve food to ten people every night.’ The Imam then said, ‘That is what I meant, O Sadir. Your serving food to your Muslim brother is equal in reward to setting free of ten slaves from the descendants of Isma‘il.’”
