Bismillahir Rahmaanir Raheem
Hadhrat ‘Abdullah Ibn ‘Umar (Radiyallahu ‘anhu) reported that Rasulullah (Sallallahu ‘alayhi wa sallam) said:
“…[Whenever a nation] lessens weights and measures [i.e. they are deceitful in business transactions], they will be afflicted with famine, price hikes and an oppressive leader.
When they refuse to pay Zakaat, they will be deprived of rain. Were it not for the animals, it will not rain [at all]…”
[Mustadrak Hakim, vol. 4 pg. 540. Sunan Ibn Majah, Hadith: 4019]
