واقِيمُوا الصَّلوةَ وَأتُوا الزَّكوة (سورة البقره 43)

iv. Warning for non-payers of Zakah:
In Quranic verse for non-payers of Zakah, Allah says:
الله فَبَرهُم بِعَد اب اليم وَالذِينَ يَكْترُونَ الذَهَبَ وَالْفِضَةَ وَلَايُنفِقُونَهَا في سَبِيلِ الله قبة
(سورة التوبة : 34)
Translation: O you who have believe, indeed many of the scholars and the monks devour the wealth of people unjustly and avert (them) from the way of Allah. And those who hoard gold and silver and spend it not in the way of Allah give them tidings of a painful punishment.
According to these verses, paying Zakah is the source of getting blessings in Akhirah and getting rid of the punishment of hellfire. There can be no other blessing greater than this one.
