Allah is the Creator of all things, and He is the Guardian over all things. (62) His are the keys of the heavens and the earth, and they who disbelieve in the revelations of Allah - such are they who are the losers. (63) (Qur'an 39: 62-63)
مَنۡ عَمِلَ صَـٰلِحً۬ا مِّن ذَڪَرٍ أَوۡ أُنثَىٰ وَهُوَ مُؤۡمِنٌ۬ فَلَنُحۡيِيَنَّهُ ۥ حَيَوٰةً۬ طَيِّبَةً۬ۖ وَلَنَجۡزِيَنَّهُمۡ أَجۡرَهُم بِأَحۡسَنِ مَا ڪَانُواْ يَعۡمَلُونَ (٩٧)
Whoever works righteousness, whether male or female, while he (or she) is a true believer (of Islâmic Monotheism) verily, to him We will give a good life (in this world with respect, contentment and lawful provision), and We shall pay them certainly a reward in proportion to the best of what they used to do (i.e. Paradise in the Hereafter). (Al Qur'an 16:97)

قُلۡ إِنَّ رَبِّى يَبۡسُطُ ٱلرِّزۡقَ لِمَن يَشَآءُ مِنۡ عِبَادِهِۦ وَيَقۡدِرُ لَهُ ۥۚ وَمَآ أَنفَقۡتُم مِّن شَىۡءٍ۬ فَهُوَ يُخۡلِفُهُۖ ۥ وَهُوَ خَيۡرُ ٱلرَّٲزِقِينَ (٣٩)
Say: "Truly, my Lord enlarges the provision for whom He wills of His slaves, and (also) restricts (it) for him, and whatsoever you spend of anything (in Allâh's Cause), He will replace it. And He is the Best of providers." (Al Qur'an 34: 39)
وَقُلِ ٱعۡمَلُواْ فَسَيَرَى ٱللَّهُ عَمَلَكُمۡ وَرَسُولُهُ ۥ وَٱلۡمُؤۡمِنُونَۖ وَسَتُرَدُّونَ إِلَىٰ عَـٰلِمِ ٱلۡغَيۡبِ وَٱلشَّہَـٰدَةِ فَيُنَبِّئُكُم بِمَا كُنتُمۡ تَعۡمَلُونَ (١٠٥)
ٱللَّهُ خَـٰلِقُ ڪُلِّ شَىۡءٍ۬ۖ وَهُوَ عَلَىٰ كُلِّ شَىۡءٍ۬ وَكِيلٌ۬ (٦٢) لَّهُ ۥ مَقَالِيدُ ٱلسَّمَـٰوَٲتِ وَٱلۡأَرۡضِۗ وَٱلَّذِينَ كَفَرُواْ بِـَٔايَـٰتِ ٱللَّهِ أُوْلَـٰٓٮِٕكَ هُمُ ٱلۡخَـٰسِرُونَ (٦٣)
And say (O Muhammad SAW) "Do deeds! Allâh will see your deeds, and (so will) His Messenger and the believers. And you will be brought back to the All-Knower of the unseen and the seen. Then He will inform you of what you used to do." (Al Qur'an 9: 105)
