And if there was any qur'an by which the mountains would be (13:31)

Almuntakhab Fi Tafsir Alquran Alkarim

And if there be a discourse that has a firm place in the realm of fact, a discourse by which mountains could be set in motion or the earth be torn apart or the dead be spoken to it would have been this Quran But, command, control, domination and decision are asserted as Allahs own. Further, do those whose hearts have been touched with the divine hand not realize that had Allah willed He could have guided mankind as a whole to His path of righteousness! Nonetheless, those whose hearts dare rise defiant against Allah -shall not cease to be bombarded with disaster hitting them directly in requital of their evil deeds or hits close enough to their homes -as a deterrent- until Allahs promised punishment comes to pass. Allah never fails to keep His promise

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

(13:31) And what (do you think) would have been the result, if We had sent a Qur'an that would have caused the mountains to move or cleft the earth asunder or made the dead speak? *47 (It is not difficult at all to show such Signs) for Allah has full power over everything. *48 Have the Believers (still any expectations of a Sign in answer to the demand of the disbelievers and) not given up all hope, (knowing) that Allah could have guided all mankind aright, *49 if He had so desired? As for the disbelievers, because of their misdeeds, one affliction or the other does not cease to visit them every now and then, or come near their home. It will go on like this untill Allah's threat come to pass. Indeed, Allah does not fail to bring about His threat.

*47) This verse has been addressed to the Believers who were feeling uneasy that no such Sign was being sent as was demanded by the disbelievers. They thought that such a Sign would convince the disbelievers and they would accept Islam. Therefore when no such Sign was sent, they became alI the more uneasy for the lack of the fulfilment of the demand that gave rise to doubts about the Prophethood of the Messenger. The question posed in this verse is meant to remove that uneasiness of the Muslims. It is like this: "Do you think that they would have embraced Islam if such and such Signs had been shown to them all of a sudden along with a Surah of the Qur'an ? Are you under the delusion that they are quite ready to accept Islam and are waiting only for such a Sign ? Do you think that those people who have failed to see the light of the Truth in the teachings of the Qur'an, in the phenomena of the universe, in the pure and spotless life of the Holy Prophet and in the wonderful change in the lives of his Companions, would see the light of the Truth in the moving of the mountains, in the cleavage of the earth and in the coming out of the dead from the graves?"
*48) "Allah has full power over everything" and can show any Sign if He so desires. He is not showing any Sign for it dces not fit in the scheme laid down for the guidance of Man. As the real object is to show Guidance to mankind through the Prophet and not to compel them to believe in the Prophethood of a Prophet, He desires that the people should gain guidance by thinking and observing wisely and not by seeing Signs.
*49) That is, "If the object had been to make human beings Believers even without consciously understanding it, Allah could have created them Believers by birth. "

اور کیا ہو جاتا اگر کوئی ایسا قرآن اتار دیا جاتا جس کے زور سے پہاڑ چلنے لگتے، یا زمین شق ہو جاتی، یا مُردے قبروں سے نکل کر بولنے لگتے؟ (اس طرح کی نشانیاں دکھا دینا کچھ مشکل نہیں ہے) بلکہ سارا اختیار ہی اللہ کے ہاتھ میں ہے پھر کیا اہل ایمان (ابھی تک کفار کی طلب کے جواب میں کسی نشانی کے ظہور کی آس لگا ئے بیٹھے ہیں اور وہ یہ جان کر) مایوس نہیں ہو گئے کہ اگر اللہ چاہتا تو سارے انسانوں کو ہدایت دے دیتا؟ جن لوگوں نے خدا کے ساتھ کفر کا رویہ اختیار کر ر کھا ہے اُن پر ان کے کرتوتوں کی وجہ سے کوئی نہ کوئی آفت آتی ہی رہتی ہے، یا ان کے گھر کے قریب کہیں نازل ہوتی ہے یہ سلسلہ چلتا رہے گا یہاں تک کہ اللہ کا وعدہ آن پورا ہو یقیناً اللہ اپنے وعدے کی خلاف ورزی نہیں کرتا
