A man began working in Dec 2023 and delayed paying zakah out of negligence. He reached nisab but does not know exactly when. Knowing missed zakah remains due for each past year, and that it’s counted from islamic months, what should he do now to calculate and pay it as soon as possible?

Ustadh AbdulAziz al-Haqqan

Estimate to the best of your ability and pay them now. Repent and never do this again akhi
