Al-A'raf · 7:131

131. Whenever the people of Pharaoh experienced wealth, healthy yields, and a thriving economy, they said: 'We have been given this because we deserve it.' But if a misfortune came upon them, such as a drought or famine, diseases, and other hardships, they would blame their bad fortune on Moses and the Children of Israel who were with him. However, the misfortunes happened to them by the decree and permission of Allah, and neither they nor Moses (peace be upon him) had any part in the affair, apart from Moses's supplications against them. But most of them do not know, saying what happens is due to other things, rather than Allah’s decree.
