4:38And those who spend their money to be seen by people, and believe neither in God nor in the Last Day. Whoever has Satan as a companion—what an evil companion.

4:39What would they have lost, had they believed in God and the Last Day, and gave out of what God has provided for them? God knows them very well.

4:59O you who believe! Obey God and obey the Messenger and those in authority among you. And if you dispute over anything, refer it to God and the Messenger, if you believe in God and the Last Day. That is best, and a most excellent determination.

4:136O you who believe! Believe in God and His messenger, and the Book He sent down to His messenger, and the Book He sent down before. Whoever rejects God, His angels, His Books, His messengers, and the Last Day, has strayed far in error.

4:162But those among them firmly rooted in knowledge, and the believers, believe in what was revealed to you, and in what was revealed before you; and the observers of prayers, and the givers of charity, and the believers in God and the Last Day—upon these We will bestow an immense reward.
