Praise be to Allah, and may peace and blessings be upon the Messenger of Allah. To proceed:
Allah تعالى does not force anyone into disbelief. Rather, the sealing, stamping, and veiling that occur over the hearts, hearing, and sight are a consequence and punishment for their previous disbelief, their choice of it, and their rejection of the messengers.
Allah تعالى says: “Rather, Allah has sealed them because of their disbelief.” [An-Nisa: 155] That is, because of their disbelief. And He سبحانه says: “So when they deviated, Allah caused their hearts to deviate.” [As-Saff: 5] Thus, He made clear that their previous deviation was a cause of the deviation of their hearts.
Allah تعالى also says: “That is because they believed and then disbelieved, so their hearts were sealed.” [Al-Munafiqun: 3]
And He says: “In their hearts is a disease, so Allah increased their disease.” [Al-Baqarah: 10]
And He says: “We will turn their hearts and eyes away, just as they did not believe in it the first time, and We will leave them wandering blindly in their transgression.” [Al-An'am: 110]
And He says: “No indeed! Rather, what they used to earn has covered their hearts like rust.” [Al-Mutaffifin: 14]
The meaning is that these people chose disbelief and turned away from the truth in the first place. When they persisted in it, Allah punished them by sealing their hearts and increasing their disease and misguidance, preventing them from benefiting from the truth, as a fitting recompense for their deeds.
Accordingly, these verses do not indicate that Allah forced them into disbelief. Rather, they indicate the servant's recompense for his choice and persistence in disbelief. A person chooses faith or disbelief and is held accountable for his choice, and all of this falls within the knowledge and decree of Allah تعالى.
And Allah تعالى knows best.
