In the creation of the heavens and the earth and the alternation of night and day, there are signs for people with intelligence: those who remember Allah, standing, sitting and lying on their sides, and reflect on the creation of the heavens and the earth: Our Lord, You have not created this for nothing.

There are men who proclaim His glory morning and evening, not distracted by trade or commerce from the remembrance of Allah and the establishment of salat (regular Prayer) and the payment of zakat (regular Charity); fearing a day when all hearts and eyes will be in turmoil – so that Allah can reward them for the best of what they did and give them more from His unbounded favour. Allah provides for anyone He wills without reckoning. The Holy Qur'an, Chapter 24,Verse 37-38
He Who created me and guides me;
He Who gives me food and gives me drink;
And when I am ill, it is He Who heals me;

He Who I sincerely hope will forgive my mistakes on the Day of Reckoning.
My Lord, give me right judgement and unite me with the righteous. The Holy Qur'an, Chapter 26,Verse 79-83
Description of people who refuse to think or ponder about this life deeply:
As for those who have taqwa, when they are bothered by visitors from Satan, they remember and immediately see clearly. But as for their brothers, the visitors lead them further into error. And they do not stop at that! The Holy Qur'an, Chapter 7,Verse 201-202
They know an outward aspect of the life of this world but are heedless of the hereafter. Have they not reflected within themselves? Allah did not create the heavens and the earth and everything between them except with truth and for a fixed term. Yet many people reject the meeting with their Lord. The Holy Qur'an, Chapter 30,Verse 7-8
Those are the people who have lost their own selves. What they invented has abandoned them. Without question they will be the greatest losers in the hereafter. As for those who believe and do right actions and humble themselves before their Lord, they are the Companions of the Garden, remaining in it timelessly, forever. The likeness of the two groups is that of the blind and deaf and the seeing and hearing. Are they the same as one another? So will you not pay heed? The Holy Qur'an, Chapter 11,Verse 21-24
The likeness of those who disbelieve is that of someone who yells out to something which cannot hear - it is nothing but a cry and a call. Deaf - dumb - blind. They do not use their intellects. The Holy Qur'an, Chapter 2,Verse 171
…They have hearts they do not understand with. They have eyes they do not see with. They have ears they do not hear with. Such people are like cattle. No, they are even further astray! They are the unaware. The Holy Qur'an, Chapter 7,Verse 179
Do you suppose that most of them hear or understand? They are just like cattle. Indeed they are even more astray! The Holy Qur'an, Chapter 25,Verse 44

Warn them of the day of bitter regret when the affair will be resolved. But they take no notice and they do not believe. The Holy Qur'an, Chapter 19,Verse 39
It is He Who shows you His signs, and sends down provision to you out of heaven. But none pay heed save those who turn unto Him repentant. The Holy Qur'an, Chapter 40,Verse 13
Say: To whom does the earth belong, and everyone in it, if you have any knowledge?
They will say: To Allah. Say: So will you not pay heed?
Say: Who is the Lord of the Seven Heavens and the Lord of the Mighty Throne?
They will say: Allah. Say: So will you not have taqwa?
Say: In whose hand is the dominion over everything, He who gives protection and from whom no protection can be given, if you have any knowledge?
They will say: Allah's. Say: So how have you been bewitched?
The fact is that We have given them the truth and they are liars. The Holy Qur'an, Chapter 23,Verse 84-90
*Taqwa: Awe or fear of Allah, which inspires a person to be on guard against wrong action and eager for actions which please Him.
Is He Who creates like him who does not create? So will you not pay heed? The Holy Qur'an, Chapter 16,Verse 17
Like those before you who had greater strength than you and more wealth and children. They enjoyed their portion; so enjoy your portion as those before you enjoyed theirs. You have plunged into defamation as they plunged into it. The actions of such people come to nothing in this world or the hereafter. They are the lost. The Holy Qur'an, Chapter 9,Verse 69

They will shout out in it, Our Lord! Take us out! We will act rightly, differently from the way we used to act! Did We not let you live long enough for anyone who was going to pay heed to pay heed? And did not the warner come to you? Taste it then! There is no helper for the wrongdoers. The Holy Qur'an, Chapter 35,Verse 37
That day Hell is produced, that day man will remember; but how will the remembrance help him?
He will say, Oh! If only I had prepared in advance for this life of mine! The Holy Qur'an, Chapter 89,Verse 23-24
