25. Sahl has narrated from Ahmad ibn al-Muthanna who has said that Muhammad ibn al-Tabari has said that a businessman from Persia who was of the friends of abu al-Hassan al-Rida wanted permission about al-khums. The Imam wrote. “In the name of Allah, the Beneficent, the Merciful Allah increases people’s sustenance and He is generous. He has guaranteed rewards for work and depression in sadness. The use of a property is not lawful unless it is used in the way Allah has made lawful. Al-Khums helps us in our religion, in the expenses of our dependents and our friends. It helps us to gift and buy protection of for our dignity against those whom we fear. Do not withheld it from us and do not deprive yourselves from our prayers as far as it is possible for you. Paying al-Khums increases you earnings, cleanses your sins and whatever you would preserve for yourselves for the day that you would need help the most. A Muslim is one who fulfills his promise to Allah. One is not a Muslim if he would say, “Yes, with his tongue but would oppose it in his heart. With peace.”
