Disbelief

Whoever turns away from Allah, his angels, his books, his messengers, has drifted into a deep and distant ruin.

4:136O ye who believe! Believe in Allah and His messenger and the Scripture which He hath revealed unto His messenger, and the Scripture which He revealed aforetime. Whoso disbelieveth in Allah and His angels and His scriptures and His messengers and the Last Day, he verily hath wandered far astray.

5:12Allah made a covenant of old with the Children of Israel and We raised among them twelve chieftains, and Allah said: Lo! I am with you. If ye establish worship and pay the poor-due, and believe in My messengers and support them, and lend unto Allah a kindly loan, surely I shall remit your sins, and surely I shall bring you into Gardens underneath which rivers flow. Whoso among you disbelieveth after this will go astray from a plain road.
