وَلَا تَتَّخِذُوٓاْ أَيۡمَٰنَكُمۡ دَخَلَۢا بَيۡنَكُمۡ فَتَزِلَّ قَدَمُۢ بَعۡدَ ثُبُوتِهَا وَتَذُوقُواْ ٱلسُّوٓءَ بِمَا صَدَدتُّمۡ عَن سَبِيلِ ٱللَّهِ وَلَكُمۡ عَذَابٌ عَظِيمٞ
And make not your oaths, a means of deception among yourselves, lest a foot may slip after being firmly planted, and you may have to taste the evil (punishment in this world) of having hindered (men) from the Path of Allah (i.e. Belief in the Oneness of Allah and His Messenger, Muhammad SAW), and yours will be a great torment (i.e. the Fire of Hell in the Hereafter).
وَلَا تَشۡتَرُواْ بِعَهۡدِ ٱللَّهِ ثَمَنٗا قَلِيلًاۚ إِنَّمَا عِندَ ٱللَّهِ هُوَ خَيۡرٞ لَّكُمۡ إِن كُنتُمۡ تَعۡلَمُونَ
And purchase not a small gain at the cost of Allah's Covenant. Verily! What is with Allah is better for you if you did but know.
مَا عِندَكُمۡ يَنفَدُ وَمَا عِندَ ٱللَّهِ بَاقٖۗ وَلَنَجۡزِيَنَّ ٱلَّذِينَ صَبَرُوٓاْ أَجۡرَهُم بِأَحۡسَنِ مَا كَانُواْ يَعۡمَلُونَ
Whatever is with you, will be exhausted, and whatever with Allah (of good deeds) will remain. And those who are patient, We will certainly pay them a reward in proportion to the best of what they used to do.
مَنۡ عَمِلَ صَٰلِحٗا مِّن ذَكَرٍ أَوۡ أُنثَىٰ وَهُوَ مُؤۡمِنٞ فَلَنُحۡيِيَنَّهُۥ حَيَوٰةٗ طَيِّبَةٗۖ وَلَنَجۡزِيَنَّهُمۡ أَجۡرَهُم بِأَحۡسَنِ مَا كَانُواْ يَعۡمَلُونَ
Whoever works righteousness, whether male or female, while he (or she) is a true believer (of Islamic 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).
