And if their evasion is difficult for you, then if you are (6:35)

Almuntakhab Fi Tafsir Alquran Alkarim

If their natural aversions and antipathies perturb you, and you are able to excavate a roadway underground or set up a ladder to ascend heavenward to bring about a sign to convince them of the truth of your mission, then by all means do it. Had Allah willed He would have united their thoughts and feelings to meditate reverence and obedience to Him and seek His guidance and spiritual union. Therefore, do not be one of those destitute of Allahs knowledge

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

(6:35) Nevertheless, if their turning away grieves you, then seek - if you can - either a way down into the earth or a ladder to the heavens, and try to bring to them some sign. *23 Had Allah so willed, He would have gathered them all to the true guidance. Do not, then, be among the ignorant. *24

And if their evasion is difficult for you, then if you are meaning

*23). The Prophet (peace be on him) saw that even though he had spent a long time admonishing his people, they did not seem inclined to heed his call. As a result he sometimes wished for the appearance of some extraordinary sign of God that would undermine the stubbornness of his people and lead them to accept his guidance. This verse embodies God's response to the Prophet's desire. He is told not to be impatient. He must persist in his striving and continue to work. in conformity with God's directive. Had it been God's purpose to work miracles, He would have done so. But God did not consider that to be either the appropriate method for bringing to a successful completion the required intellectual and moral revolution or for the evolution of a sound, healthy civilization. Well, then, if the Prophet (peace be on him) could not bear patiently with the attitude of stubbornness and rejection prevalent among his people, and if he thought it necessary to make them witness a tangible sign of God, let him muster all his strength and try to cleave the earth, or climb a ladder to the heaven and bring forth a miracle powerful enough to change the unbelief of the unbelievers into belief. He is told, however, that in this regard he should not expect God to fulfil his wish, for such things have no place in God's scheme.
*24). Had it been required that all people should be driven to the Truth, there would have been no need to send Prophets, to reveal heavenly Books, to direct believers to engage in struggles against unbelievers, and to make the message of Truth pass through the necessary stages until fulfilment is reached. The result could have been achieved by a single sign of God's creative will. God, however, did not want things to happen that way. He preferred the Truth to be set before people with its supporting arguments so that by a proper exercise of their rational judgement, they should recognize it for what it was and thereafter freely choose to embrace it as their faith. By moulding their lives in conformity with this Truth such people should demonstrate their moral superiority over the devotees of falsehood. They should continually attract men of sound morals by the force of their arguments, by the loftiness of their ideals, by the excellence of their principles and by the purity of their lives. They should thus reach their goal - the establishment of the hegemony of the true faith - by the natural and gradual escalation of strife against falsehood. God will guide them in the performance of this task and will provide them with whatever help they merit during the various stages of their struggle. But if anyone wishes to evade this natural course and wants God to obliterate corrupt ideas and to spread healthy ones in their stead, to root out a corrupt civilization and put a healthy one in its place by exercising His omnipotent will, let him know that this will not come about. The reason is that such is contrary to the scheme according to which God has created man as a responsible being, bestowed upon him a degree of power which he may exercise, granted him the freedom to choose between obedience and disobedience to God, awarded him a certain term of life in order to demonstrate his worth, and determined that at an appointed hour He will judge him for either reward or punishment in the light of his deeds.

تاہم اگر ان لوگوں کی بے رخی تم سے برداشت نہیں ہوتی تو اگر تم میں کچھ زور ہے تو زمین میں کوئی سرنگ ڈھونڈو یا آسمان میں سیڑھی لگاؤ اور ان کے پاس کوئی نشانی لانے کی کوشش کرو اگر اللہ چاہتا تو ان سب کو ہدایت پر جمع کر سکتا تھا، لہٰذا نادان مت بنو
