Hazrat Shaikh Moulana Muhammad Zakariyya (rahmatullahi ‘alaihi) mentioned: “If one does not discharge one’s zakaat from one’s wealth, then that zakaat eventually will destroy the entire wealth, either by a fire burning it, or by being spent in court cases, or on medical expenses or some other unnecessary purposes. On the other hand, if one discharges the zakaat, then Allah Ta’ala will bless one with barkah in one’s wealth and the wealth will not decrease.” (Malfoozaate Hazrat Shaikh 1/39)
