Surah An-Nahl Verse 95

وَلَوْ شَآءَ اللَّهُ لَجَعَلَكُمْ أُمَّةً وَحِدَةً وَلـكِن يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ وَلَتُسْـَلُنَّ عَمَّا كُنتُمْ تَعْمَلُونَ - وَلاَ تَتَّخِذُواْ أَيْمَـنَكُمْ دَخَلاً بَيْنَكُمْ فَتَزِلَّ قَدَمٌ بَعْدَ ثُبُوتِهَا وَتَذُوقُواْ الْسُّوءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ اللَّهِ وَلَكُمْ عَذَابٌ عَظِيمٌ - وَلاَ تَشْتَرُواْ بِعَهْدِ اللَّهِ ثَمَناً قَلِيلاً إِنَّمَا عِنْدَ اللَّهِ هُوَ خَيْرٌ لَّكُمْ إِن كُنْتُمْ تَعْلَمُونَ - مَا عِندَكُمْ يَنفَدُ وَمَا عِندَ اللَّهِ بَاقٍ وَلَنَجْزِيَنَّ الَّذِينَ صَبَرُواْ أَجْرَهُمْ بِأَحْسَنِ مَا كَانُواْ يَعْمَلُونَ

(93. And had Allah willed, He would have made you (all) one nation, but He allows whom He wills to stray and He guides whom He wills. But you shall certainly be called to account for what you used to do.)

(94. And do not make your oaths a means of deception among yourselves, resulting in the slip of a foot after it was firmly planted, and you taste the evil of having hindered from the path of Allah, and you will suffer a terrible punishment.)

(95. And do not use an oath by Allah for the purchase of little value, what is with Allah is better for you if you only knew.)

(96. Whatever you have will be exhausted, and what is with Allah will remain. And to those who are patient, We will certainly grant them their rewards in proportion to the best of what they used to do.)

If Allah had willed, He would have made all of Humanity one Nation

Allah says:

وَلَوْ شَآءَ اللَّهُ لَجَعَلَكُمْ

(And had Allah willed, He would have made you) meaning - O mankind,

أُمَّةً وَحِدَةً

((all) one nation,) This is like the Ayah:

وَلَوْ شَآءَ رَبُّكَ لآمَنَ مَن فِى الاٌّرْضِ كُلُّهُمْ جَمِيعًا

(And had your Lord willed, all of those on earth would have believed together.) 10:99, meaning, He could have created harmony among them, and there would not be any differences, conflicts or hatred between them.

وَلَوْ شَآءَ رَبُّكَ لَجَعَلَ النَّاسَ أُمَّةً وَاحِدَةً وَلاَ يَزَالُونَ مُخْتَلِفِينَ

إِلاَّ مَن رَّحِمَ رَبُّكَ وَلِذلِكَ خَلَقَهُمْ

(And if your Lord had so willed, He would surely, have made mankind one Ummah nation or community, but they will not cease to disagree. Except him on whom your Lord has bestowed His mercy, and for that did He create them.) (11:118-119) Similarly, Allah says here:

وَلـكِن يُضِلُّ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ

(but He allows whom He wills to stray and He guides whom He wills. ) Then on the Day of Resurrection, He will ask them all about their deeds, and will reward or punish them even equal to a scalish thread in the long slit of a date stone or the size of a speck on the back of a date stone, or even a thin membrane of the date stone.

The Prohibition on taking an Oath for Purposes of Treachery

Then Allah warns His servant against taking oaths as means of deception, i.e., using them for treacherous purposes, lest a foot should slip after being firmly planted. This is an analogy describing one who was on the right path but then deviated and slipped from the path of guidance because of an unfulfilled oath that involved hindering people from the path of Allah. This is because if a disbeliever were to find that after having agreed to a covenant, then the believer betrayed him, then the believer will have hindered him from entering Islam. Thus Allah says:

وَتَذُوقُواْ الْسُّوءَ بِمَا صَدَدتُّمْ عَن سَبِيلِ اللَّهِ وَلَكُمْ عَذَابٌ عَظِيمٌ

(and you taste the evil of having hindered from the path of Allah, and you will suffer a terrible punishment.)

Do not break Oaths for the sake of Worldly Gain

Then Allah says:

وَلاَ تَشْتَرُواْ بِعَهْدِ اللَّهِ ثَمَناً قَلِيلاً

(And do not use an oath by Allah for the purchase of little value.) meaning, do not neglect an oath sworn in the Name of Allah for the sake of this world and its attractions, for they are few, and even if the son of Adam were to gain this world and all that is in it, that which is with Allah is better for him, i.e., the reward of Allah is better for the one who puts his hope in Him, believes in Him, seeks Him and fulfills his oaths in the hope of that which Allah has promised. This is why Allah says:

إِن كُنتُمْ تَعْلَمُونَمَا عِندَكُمْ يَنفَدُ

(if you only knew. Whatever you have will be exhausted,) meaning, it will come to an end and will vanish, because it is only there for a certain, limited time.

وَمَا عِندَ اللَّهِ بَاقٍ

(and what is with Allah will remain.) meaning, His reward for you in Paradise will remain, without interruption or end, because it is eternal and will never change nor disappear.

وَلَنَجْزِيَنَّ الَّذِينَ صَبَرُواْ أَجْرَهُمْ بِأَحْسَنِ مَا كَانُواْ يَعْمَلُونَ

(And to those who are patient, We will certainly grant them their rewards in proportion to the best of what they used to do. ) Here the Lord swears, with the Lam of affirmation, that He will reward the patient for the best of their deeds, i.e., He will forgive them for their bad deeds.
