What is the right pathway for human beings to go to the paradise?

 

Verses 1-5 of Chapter 2:

Alif. Lam. Mim. This is the Book of Allah: there is no doubt about it. It is guidance to Godfearing people, who believe in the unseen, establish the Salats and expend (in Our way) out of what We have bestowed on them; who believe in the Book We have sent down to you (i.e. the Qur'an) and in the Books sent down before you, and firmly believe in the Hereafter. Such people are on the right way from their Lord and such are truly successful.

Verse 177 of Chapter 2:

It is no virtue. That you turn your faces towards the east or the west, but virtue is that one should sincerely believe in Allah and the Last Day and the Angels and the Book and the Prophets and, out of His love, spend of one's choice wealth for relatives and orphans, for the needy and the wayfarer, for beggars and for the ransom of slaves, and establish the Salat and pay the Zakat. And the virtuous are those who keep their pledges when they make them and show fortitude in hardships and adversity and in the struggle between the Truth and falsehood; such are the truthful people and such are the pious.

Verses 151-153 of Chapter 6:

(O Muhammad,) say to them, "Come, I will recite what limits your Lord has set for you." (He has enjoined:) (1) That you should not set up anything as a partner with Him, (2) and you should treat your parents kindly, (3) and you should not kill your children for fear of poverty, for We provide sustenance for you and will provide sustenance for them also, (4) and you should not go near indecent things whether they be open or hidden, (5) and you should not kill any living being whom Allah has forbidden to kill except by right. These are the things which He has enjoined on you: it may be that you use your common sense. And He has enjoined:(6) that you should not go near the property of an orphan except in the best way,'until he reaches his maturity.(7) and you should use a full measure and a just balance. We charge one only with that much responsibility that one can bear, (8) and whatever you say should be just, even if it is concerning your own relatives, (9) and you should fulfill your covenant with Allah. Allah has enjoined these things on you so that you may follow the admonition. (10) And Allah also enjoins: "This way alone is My Right Way; therefore you should follow this Way and should not follow other ways lest they should lead you astray from His Way. This is what Allah has enjoined on you so that you may avoid crooked ways.
