Rational proofs are part of the scientific miracles in the holy Qur'an, let us read………
There were many events that occurred in front of atheists but they didn't give any obstruction about it and they accepted it without any comment, one of these events what Allah almighty said about Abû Lahab in the following verses: ( Perish the two hands of Abû Lahab (an uncle of the Prophet) and perish he* His wealth and his children will not benefit him!* He will be burnt in a Fire of blazing flames!*And his wife, too, who carries wood (thorns of Sa‘dân which she used to put on the way of the Prophet, or use to slander him)* In her neck is a twisted rope of Masad (palm fibre))( Sûrat Al-Masad-verse1-5), when He almighty promised Abû Lahab that he will be burnt in Fire as he will die as an atheist, in fact it was a challenge for all human as this Sûrat was descended at the beginning of Islam and many years before the death of Abû Lahab, and Abû Lahab heard that verse many times but he didn't think to enter Islam as by that action the whole religion might be destroyed but the one who said that verse is not a human but He is Allah who knows past, present and the future who knows defiantly that Abû Lahab will never believe with prophet Mohamed(peace be upon him).
Also Abû Lahab was the uncle of the Prophet and if Mohamed was the author of the Qur'an (as disbelievers and atheists want to believe), the prophet might promise him to enter the heaven because of the relatively between both of them but Allah almighty is the one who descended Qur'an.
Also, in another event Allah almighty tells us about very strange cosmic phenomenon which is the splitting of the moon as He almighty says: (The Hour has drawn near, and the moon has been cleft asunder (the people of Makah requested Prophet Muhammad to show them a miracle, so he showed them the splitting of the moon).* And if they see a sign, they turn away, and say: "This is continuous magic."* They belied (the Verses of Allah - this Qur'an), and followed their own lusts. And every matter will be settled (according to the kind of deeds: good deeds will take their doers to
In fact, when this verse was descended, no one in Makah from atheists and disbelievers did say that Mohamed is a liar, but they accepted what the prophet said because they indeed saw the splitting of the moon by their naked eyes and that was by many groups in different places.
So that disbelievers didn't say he is a liar but they said it is a (continuous magic), on the other side if the believers didn't see this phenomenon and heard some verses about it , they may be doubted about their prophet and the religion of Islam, but they indeed saw that event by their eyes.
Also, another proof that the splitting of the moon was definitely happened is that the companions of the prophet used to ask him about the meaning of verses of Qur'an and the different events which happened in the past during the 23 years of life of the prophet in Islam but they didn’t ask him any question because by logic they saw that event by their eyes.
