And do not be like she who untwisted her spun thread after (16:92)

Almuntakhab Fi Tafsir Alquran Alkarim

Do not be like the unstable workwoman who unravels and breaks the strands of her woven fabric after she has manufactured it in a loom by crossing the warp and the weft and interlaced them very strongly. What a tangled web you weave when first you practice to deceive. You use your oaths among yourselves with the guilt of deception residing in the intention; you break and dishonour your vows with the weak when you find them more advantageous with the strong. This is unexcusable nor is it in conformity with Islamic principles. Allah tests your prudence and in Day of Judgment shall He clear up matters with which you were at variance

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(16:92) Do not behave like that woman who had spun yarn laboriously and then had herself broken it into pieces. *90 You make your mutual oaths a means of mutual deceit in your affairs so that one people might take undue advantage over the other whereas Allah puts you to trial by these pledges. *91 Allah will certainly reveal to you the truth about all your differences on the Day of Resurrection. *92

*90) In this verse, Allah has enjoined three kinds of Covenants which have been mentioned in the order of their importance. The first of these Covenants is the one between man and his Allah which is the most important of all. The second in importance is the Covenant between one man or one group of men and another man or another group of men, which is taken with Allah as a witness or in which the name of God has been used. The third Covenant is that which has been made without using Allah's name. Though this is third in importance, its fulfilment is as important as that of the first two and the violation of any of these has been prohibited.
*91) In this connection it should be noted that AIlah has rebuked the people for the worst form of violation of treaties which has been creating the greatest disorder in the world. It is a pity that even "big" people consider it to be a virtue to violate treaties in order to gain advantages for their people in political, economic and religious conflicts. At one time the leader of one nation enters into a treaty with another nation for the interest of his own people but at another time the same leader publicly breaks the very same treaty for the interest of his people, or secretly violates it. It is an irony that such violations are made even by those people who are honest in their private lives. Moreover, it is regretable that their own people do not protest against them; nay, they eulogize them for such shameful feats of diplomacy. Therefore, Allah warns that every such treaty is a test of the character of those who enter into it, and of their nations. They might gain some apparent advantage for their people in this way, but they will not escape their consequences on the Day of Judgment.
*92) This is to warn that decision about differences and disputes that lead to conflict, will be made on the Day of Judgment. Therefore, these should not be made an excuse to break agreements and treaties. Even if one is wholly in the right and the opponent is wholly in the wrong, it is not right for the former to break treaties or make false propaganda or employ other deceitful methods to defeat the other. If one does so, it will go against him on that Day because righteousness demands that one should not only be right in one's theories and aims but should also use right methods and employ right means. This warning has especially been given to those religious groups and sects who always suffer from this misunderstanding that they have a right to defeat their opponents because they are on the side of God and their opponents are rebels against Allah: therefore, there is no obligation on them to stick to their treaties with their opponents. This was what the Arab Jews practiced, declaring, "There is no moral obligation on us in regard to the pagan Arabs, and we are rightly entitled to practise dishonesty and deceit that might be of advantage to us and harmful to the disbelievers".

تمہاری حالت اُس عورت کی سی نہ ہو جائے جس نے آپ ہی محنت سے سوت کاتا اور پھر آپ ہی اسے ٹکڑے ٹکڑے کر ڈالا تم اپنی قسموں کو آپس کے معاملات میں مکر و فریب کا ہتھیار بناتے ہو تاکہ ایک قوم دوسری قوم سے بڑھ کر فائدے حاصل کرے حالاں کہ اللہ اس عہد و پیمان کے ذریعہ سے تم کو آزمائش میں ڈالتا ہے، اور ضرور وہ قیامت کے روز تمہارے تمام اختلافات کی حقیقت تم پر کھول دے گا
