Zakat on Monthly Pension Income

Short answer: Zakat is not on income but on savings. A monthly pension is like a salary: what gets spent carries no zakat; what accumulates, keeps your total above nisab and survives a lunar year is zakated at 2.5%. Details: Islam has no income-tax-style levy on earnings; zakat attaches to wealth remaining at year's end. Practical method: fix a hijri zakat day; that day add bank balances + cash + other zakatable assets; if above the nisab (value of 87.48 g gold or 612.36 g silver), pay 2.5%. No need to track a separate hawl for each month's inflow — one annual reckoning simply pays some zakat early, which is permissible. Evidence: Quran 2:219 ('say: the surplus'); Ibn Majah 1792 (hawl); the practical method taught by Shaykh Ibn Baz and Shaykh al-Uthaymin for salaries and periodic income.
