Is unintentionally pushing the Mus'haf, along with whispers about uttering a word that disparages the Qur'an, considered an act of disbelief (kufr)?

A Muslim must guard his tongue, speak good, and remain silent about evil, according to the Prophet, peace and blessings be upon him: "Whoever believes in Allah and the Last Day, let him speak good or remain silent." This is because the harvests of tongues are what cause people to be thrown into the Fire. He must also respect the Book of Allah and glorify His rituals. Allah the Almighty does not hold a Muslim accountable for what he utters while asleep or by mistake, as the Prophet, peace and blessings be upon him, said: "Indeed, Allah has overlooked for my Ummah mistakes, forgetfulness, and what they are compelled to do." Therefore, what happened to you is not considered disbelief (kufr). It is advisable to fear Allah, accustom your tongue to speak good, and distance yourself from obsessive thoughts.
