The Quran explains the need of belief in God and draws attention to the proofs of His existence. It emphasizes that God has always sent down His word by means of revelation. If God were to cease to manifest His attributes through the prophets and their followers, firm faith in the existence of God would disappear. It is imperative, therefore, that so long as mankind continue to exist, divine revelation should continue to descend upon some of them.

25:64 And the servants of the Gracious God are those who walk on the earth in a dignified manner, and when the ignorant address them, they say, ‘Peace!’

25:65 And who spend the night before their Lord, prostrate and standing.

25:66 And who say, ‘Our Lord, avert from us the punishment of Hell; for the punishment thereof is a lasting torment.

25:67 ‘It is indeed evil as a place of rest and as an abode’;

25:68 And those who, when they spend, are neither extravagant nor niggardly but moderate between the two;

25:69 And those who call not on any other God along with Allah, nor kill a person that Allah has forbidden except for just cause, nor commit adultery (or fornication), and he who does that shall meet with the punishment of sin.

25:70 Doubled to him will be the punishment on the Day of Resurrection, and he will abide therein disgraced,

25:71 Except those who repent, and believe and do good deeds; for as to these, Allah will change their evil deeds into good deeds; and Allah is Most Forgiving, Merciful;

25:72 And those who repent and do good deeds, indeed turn to Allah with true repentance;

25:73 And those who bear not false witness, and when they pass by anything vain, they pass on with dignity;

25:74 And those who, when they are reminded of the Signs of their Lord, fall not deaf and blind thereat;

25:75 And those who say, ‘Our Lord, grant us of our wives and children the delight of our eyes, and make us a model for the righteous.’

25:76 It is such as will be rewarded a high place in Paradise because they were steadfast, and they will be received therein with greeting and peace,

25:77 Abiding therein. Excellent it is as a place of rest and as an abode.

25:78 Say to the disbelievers: ‘But for your prayer to Him my Lord would not care for you, you have indeed rejected the truth and the punishment of your rejection will now cleave to you.’

23:2 Surely, success does come to the believers,

23:3 Who are humble in their Prayers,

23:4 And who shun all that which is vain,

23:5 And who are active in paying the Zakat,

23:6 And who guard their chastity –

23:7 Except from their wives or what their right hands possess, for then they are not to be blamed;

23:8 But those who seek anything beyond that are the transgressors –

23:9 And who are watchful of their trusts and their covenants,

23:10 And who are strict in the observance of their Prayers.

23:11 These are the heirs,

23:12 Who will inherit Paradise. They will abide therein.
