9. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan ibn Yahya from abu al-Hassan al-Rida (a.s.), who has said the following
“The narrator has said, ‘Once, one of the servants of abu al-Hassan al-Rida (a.s.), came in and the Imam asked, “Have you spent (for deserving causes) anything today?” He (the servant) replied, “No, I have not done so.” Abu al-Hassan (a.s.), then said, “Wherefrom will Allah then grant us replacement? You must spend (for deserving causes), even if it would be one dirham only.’””
