As we are all sinners and there are no religion in this planet which will take you to heaven. God is just and never lies. Without any justification or reason He won't forgive your sin. Fasting, Praying, Donations, Visiting Holy Places will NOT take you to heaven. There are NO any prophets in any religions gave any right indication to go to heaven.
When even Mohammad died he had no idea where his allah is going to put him. That is why he told his followers to pray five times a day for his eternal rest.
If some one had no idea where he is going then will you follow him?
But putting trust in Jesus will free you from all sort sins and bondage of law because only Jesus paid the penalty in the mountain of the Culvery and third day He rose from death and freed us from our sins. Through Him we call God a Father. What a wonderfull God we have. Christinity is NOT a religion but a relationship with God. (Like father and son).
