All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Some scholars are of the view that there is no Zakaat due at all on the amount that is deducted from the salary for retirement.
Shaykh Ibn 'Uthaymeen was asked: “Is there any Zakaat on the money of retirement from the government?”
He replied:
“There is no Zakaat on the retirement money that is taken from the salary, because its owner cannot withdraw it except under certain conditions. It is like a debt that is due on an insolvent person, and there is no Zakaat on the debt that is on the insolvent. However, once he receives it, it is better to pay Zakaat on it once for one year, in order to be on the safe side.” [End of quote] (Majmoo’ Al-Fataawa)
Allah knows best.
