We know that many prophets performed miracles and many people didn't believe these prophets because they thought it was all magic. But will Allah punish these people? Why would Allah punish them in the afterlife? In the Quran, Allah says that he will not charge a soul beyond it's capability. So if a person is not capable of distinguishing between miracle and magic, why should Allah punish him? It just means that Allah needs to show a stronger sign.
If you do not believe in Prophet's miracle, you are not believing in Allah's ability to do that. Prophets didn't do any miracle on their own, they only did what Allah told them to and everything else is done by Allah himself.
Moses only threw the staff, Allah changed it to snake, not Moses. Ibrahim was thrown into fire, Allah changed it in to a peaceful area, not Ibrahim. Jesus just touched the people, Allah cured them from their disability and disease, not Jesus.
If you don't believe in any of those, you are not believing in Allah's ability to do those, nobody can believe that a fire wont burn you, but the creator of fire itself can change it. If Allah can make a thing to burn something, he can also make the same thing not to do it. So it is about Allah's ability, not just prophets miracle.
What do you mean by incapable of thinking that? Allah gave humans the ability to think for the sake of thinking about Allah's ability to do things and believe in him for that.
Human didn't create fire from nothing, he is using Allah's creation of physics to create it. If someone can believe that Allah can create fire from nothing and make it hot and burn things, then he can also believe that he can make the same thing not hot and do nothing. It is within human's thinking capability.
so believer should believe in prophet's miracle, otherwise they are not believing fully and will be asked questions about them in Judgement day.
once childishly Musa A.S asked Allah to show himself to Musa A.S Allah said no you cannot see,he insisted then on mount Judi Allah swt just showed his shadow the mountain turned to dust and Musa A.S was unconcious for 40 days.
he could have died if Allah willed.but Allah saved him and left unconsious.s you said yourself Allah does not give work beyond there capability you have been given some signs you can understand others can more or less with there capabilities.
other Prophets were given signs as they have not been given complete books as we have. we have been given Quran which covers all types fields all of them. be it science or engineering or pycological or emotional or etymological etc.it gives what will happen in future with you and all the universe in detail manner. are you capable to understand. the sign this ummah has been given is of understanding. you plant a seed it grows in herb then tree then gives out fruits etc it is periodical to understand you have to sit daily looking after it it is persistantly happening you see or not but it is magic a seed destroys itself (can you see) a stem comes out of it (can you see) it grows leaves (can you see) it grows flowers (can you see) it grows with more leaves (can you see) it is all magic it each phase destroys and give shape to new phase.it is uniformly happening
UNDER WHOSE EYES ? who controls excess or less food to it to grow. so is your case Allah gives you what you can understand you dont understand and straight away assume it is wrong. that is un-uniform.
