How to cure the extravagance and waste that has afflicted the Muslims?

Question:
As you mentioned in the lecture regarding the causes of the challenges, the extravagance and waste that has afflicted the Muslims, especially the wealthy countries, how is the cure for that?

Answer:
The cure for that is to fear Allah the Exalted, and to spend wealth in its path, in obedience to Allah and His Messenger, not in what Allah has forbidden, such as gambling, intoxicants, lewdness, extravagance, and waste. No, rather wealth is preserved and spent in obedience to Allah, in jihad against the enemies of Allah, in building the mosques that people need, building schools, paying off the debts of debtors and the insolvent, and other such avenues of good. There are many avenues of good. It is obligatory for the people of wealth to fear Allah in it, and that it not be spent in the sins of Allah the Mighty and Majestic, neither by states nor by individuals. But we ask Allah to rectify the condition of everyone. If people had been upright upon the religion of Allah in everything, no one would have done so. Yes. Allah is the Helper.
