Indeed, those who dispute concerning the signs of Allah without [any] authority (40:56)

Almuntakhab Fi Tafsir Alquran Alkarim

Those who contend with opposing arguments against Allahs signs and seem resolved to dispute the truth of His revelations without being endowed with authority, simply vent their feelings overflowing with the sense of pride and inordinate self-esteem but attaining no end. Therefore, commit yourself O Muhammad, to Allah counter to their falsehood. He is AL-Sami’ (with unlimited audition), and AL-Bassir (the vigilant who sees all things)

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

(40:56) Verily those who dispute regarding the Signs of Allah without any evidence that might have come to them, nothing but vain pride fills their hearts. Yet they shall never be able to satisfy the pride *75 with which they are puffed up. *76 So seek refuge with Allah. *77 Verily He is All-Hearing, All-Seeing.

*75) That is, `The real cause for their opposition without any argument and Their irrational, crooked argumentation is not that they do not understand the myths and the themes of goodness and reform being presented before there in the form of the Revelations of Allah; therefore, they dispute about them in good faith in order to understand them; but the actual reason for their wrong attitude is that Their self-conceit dces not permit them tolerate that while they are living in Arabia the guidance and leadership of Muhammad (upon whom be Allah's peace) be accepted and acknowledged and ultimately one day they themselves should have to accept the leadership of the person as against whom they think they have a greater right to be the chiefs and leaders. That is why they are straining every nerve not to let Muhammad (upon whom be Allah's peace) have his way, and they do not hesitate to use any mean device whatever for the purpose.
*76) In other words it means: `He whom Allah has made great, will remain great, and the efforts of the small people who are trying to establish their superiority, will ultimately end in failure."
*77) That is, `Just as Moses had become free from fear and anxiety after invoking Allah Almighty's help and refuge against Pharaoh's threats, so should you also seek His help and refuge against the threats and conspiracies of the chiefs of the Quraish, and then should busy yourself in raising His word being free from every anxiety."

حقیقت یہ ہے کہ جو لوگ کسی سند و حجت کے بغیر جو اُن کے پاس آئی ہو، اللہ کی آیات میں جھگڑے کر رہے ہیں اُن کے دلوں میں کبر بھرا ہوا ہے، مگر وہ اُس بڑائی کو پہنچنے والے نہیں ہیں جس کا وہ گھمنڈ رکھتے ہیں بس اللہ کی پناہ مانگ لو، وہ سب کچھ دیکھتا اور سنتا ہے
