When a person committed kufr what are the consequences?

Answer

When a person becomes a kaafir – Allah forbid – he loses his Imaan, and his nikah terminates forthwith. He has to repent, renew his Imaan and also his nikah. All his past deeds are obliterated by his kufr. Even if he had performed Hajj before, he will again have to perform Hajj if he is by the means. A Muslim who reneges from Islam is termed murtad. If he dies without having repented and renewing his Imaan, he will suffer everlasting damnation in the Hereafter.
