What are the characteristics of God-fearing people (Muttaqin) for whom God has prepared 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.

Verses 133-136 of Chapter 3
And march forth in the way (which leads to) forgiveness from your Lord, and for Paradise as wide as the heavens and the earth, prepared for the Muttaqin (God-fearing people). Those who spend (in Allah's cause) in prosperity and in adversity, who repress anger, and who pardon men; verily, Allah loves the Muhsinin (the good-doers). And those who, when they have committed Fahishah (immoral sin) or wronged themselves with evil, remember Allah and ask forgiveness for their sins; and none can forgive sins but Allah, and do not persist in what (wrong) they have done, while they know. For such, the reward is forgiveness from their Lord, and Gardens with rivers flowing underneath (Paradise), wherein they shall abide forever. How excellent is this reward for the doers (of good).

Verses 1-11 of Chapter 23  
Successful indeed are the believers. Those who humbly cry in their prayers. And who do not incline towards indecent matters. And who pay the (obligatory) charity. And who guard their private organs. Except from their wives or the legal bondwomen that they possess, for then there is no blame upon them. So whoever desires more than these two - they are crossing the limits. And those who keep proper regard for their trusts and their pledges. And who guard their prayers. They are the inheritors. Those who will get the inheritance of Paradise; they will abide in it forever.
