Thalika bi-annahu kanat ta'teehim rusuluhum bilbayyinati faqaloo abasharun yahdoonana fakafaroo watawallaw wastaghna (surah Taghabun: 6)

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

(64:6) This was because their Messengers would come to them with Clear Signs, *11 but they would say: 'Shall mortals (like ourselves) guide us to the Right Way?' *12 They rejected the Truth and turned away. Thereupon Allah became unconcerned with them, for Allah is Self-Sufficient, Innately Praiseworthy. *13

Zaalika bi annahoo kaanat taateehim Rusuluhum bilbaiyinaati faqaaloo a basharuny yahdoonanaa fakafaroo wa tawallaw; wastaghnal laah; wallaahu ghaniyyun hameed

*11) The word bayyinet as used in the original has a vast meaning. Bayyin (sing. of bayyinat in Arabic is something which is very clear and manifest. Saying about the Prophets that they came with bayyinat gives the meaning that firstly, they brought such manifest signs as bore clear testimony to their having been appointed by AIIah; secondly, they presented whatever they presented with rational and clear arguments; thirdly, there was no ambiguity in their teaching; they clearly explained what was the truth and what was falsehood. what was lawful and what was unlawful, what path man should follow and what he should avoid.
*12) This was then the foremost and basic cause of their degenenation and ruin Mankind could not have known the right course of action in the world unless their Creator gave them the correct knowledge, and there could be no practical means of bestowing such knowledge by the Creator unless He blessed some of the human beings with the knowledge and entrusted them with the duty to convey it to other human beings. For this purpose He sent the Prophets with the manifest Signs bayyinat) so that there was-no reasonable ground for the people to doubt their being on the truth. But the people refused to believe that a human being could be a Messenger of God. Then, obviously there could be no other way for them to receive guidance. (For further explanation, see E.N. 11 of Surah Ya Sin). In this connection, however, a strange manifestation of the ignorance and folly of human beings is seen. They have in fact, never shown any hesitation in accepting the guidance of men, so much so that they have caryed out gods of wood and stone according to their guidance, they have made human beings themselves God, the incarnation of God, even son of God. and they have adopted such strange viewpoints by following the guidance of their mis-leaders blindly, which ruined human civilization and morals altogether. But when the Messengers of God came to them with the truth, and they presented the pure Truth before them without any selfish motive, they said, "Shall mere human beings show us guidance?" This amounted to saying that if a human begin misled them, they would follow his guidance willingly, but if he showed the right path to them, his guidance was not acceptable.
*13) That is, when they treated the guidance sent down by Allah with indifference, then AIlah also became indifferent to them and did not care what pit they fell in. AIIah did not stand in need of their aknowledging Him God to sustain and support His Godhead. Nor was He in need of their worship, nor of their praise and adoration. He, in fact, willed to show them the right path only for their own good and well-being. But when they turned away from it, AIlah also became heedless of them. Then, neither He gave them guidance, nor remained responsible for their protection, nor saved them from being afflicted with calamities, nor prevented them from bringing about their own ruin for they themselves were not keen for His guidance and help.
