Humans Given The Choice of Free Will

I think I first heard in talk by Dr. Zakir Naik that us humans were given a choice of free will (perhaps between free will and being an angel). Obviously, we chose free will. To me, this made absolute sense: Allah would never leave a loophole where an individual who is about to go to Hell may say "Oh Allah! I did not ask for any of this!" To my knowledge there are two verses in the Quran that are related to this matter. The first one is indirectly related: > **And [mention] when your Lord took from the children of Adam - from their loins - their descendants and made them testify of themselves, > [saying to them], "Am I not your Lord?" They said, "Yes, we have > testified." [This] - lest you should say on the day of Resurrection, > "Indeed, we were of this unaware." [7:172]** However, *I think,* the following verse is related to my question: > **We offered Our Trust (Our deputation) to the heavens, to the earth, and to the mountains, but they could not bear this burden and were > afraid to accept it. Mankind was able to accept this offer but he was > unjust to himself and ignorant of the significance of this Trust. > [33:72]** Could this verse be talking about the the choice of free will? (And, of course, all the responsibilities that comes with it, and that is why mountains did not accept it, and that is why mankind is considered unjust to himself and ignorant about the Truth.) **My Questions:** 1. What is the scholarly view about this verse (33:72)? 2. With respect to my original question and Dr. Zakir Naik's comment: Is there another Quranic verse or hadith (if not, any view from the great scholars of the past) that would unambiguously shed light on this topic (that mankind offered a choice between free will and something else)?
