lol.. Muslims can't charge interest. Interest is a form of oppression.

In Islam, usury (known as "riba" in Arabic) is strictly prohibited. Riba refers to any guaranteed interest on loaned money, which is seen as exploitative and unjust. The prohibition of riba is based on several Quranic verses and Hadith (sayings and actions of the Prophet Muhammad, peace be upon him).

Quranic Verses on Riba Condemnation of Riba: The Quran clearly condemns riba and warns of severe consequences for those who engage in it. For example:

Surah Al-Baqarah (2:275-279):

Those who consume interest cannot stand [on the Day of Resurrection] except as one stands who is being beaten by Satan into insanity. That is because they say, "Trade is [just] like interest." But Allah has permitted trade and has forbidden interest. So whoever has received an admonition from his Lord and desists may have what is past, and his affair rests with Allah. But whoever returns [to dealing in interest or usury] - those are the companions of the Fire; they will abide eternally therein.

Allah destroys interest and gives increase for charities. And Allah does not like every sinning disbeliever.

Indeed, those who believe and do righteous deeds and establish prayer and give zakah will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.

O you who have believed, fear Allah and give up what remains [due to you] of interest, if you should be believers.

And if you do not, then be informed of a war [against you] from Allah and His Messenger. But if you repent, you may have your principal - [thus] you do no wrong, nor are you wronged.

Surah An-Nisa (4:161):

And [for] their taking of usury while they had been forbidden from it, and their consuming of the people's wealth unjustly. And We have prepared for the disbelievers among them a painful punishment.

In conclusion, in Islam, usury or interest (riba) is unequivocally prohibited due to its exploitative nature and potential to cause social and economic injustice. The Quran and Hadith provide clear guidance on avoiding riba and encourage ethical alternatives that promote fairness, mutual benefit, and social welfare. Islamic banking and finance have developed various instruments to adhere to these principles while providing viable financial services.
