When a Prophet performs an action that is impossible to perform to prove his prophecy and it astonishes the Kaafirs, it is known as a “Maujizaa”.For example,to bring back to life the dead or to split the moon into two with the movement of the finger.
If these types of actions are performed by a Wali (Friend of Allah Ta’ala), then it is known as a”Karamat”.
If they are performed by an ordinary person or wrongdoer or a kaafir, then it is known as ”istidraj”.
when people see a Maujizaa, truth of a Prophet is accepted .
False liars who claim to be a Prophet cannot perform these types of miracles .Allah Ta’ala never gives the false claimants of Prophethood the power to perform Maujizaas, otherwise one would not be able to distinguish the difference between the true Prophets and false claimants.
Kitaabs were revealed to the Ambiya to teach and educate their nations. The big books are called “Kitaabs”whilst the small ones are called “Sahafis”.
Muslims believe in all the Books sent by Allah Ta’ala . The Tauraat was revealed to Hazrath Moosa (alaihis salaam); the Zaboor was revealed to Hazrath Dawood (alaihis salaam) ;the Injeel was revealed to Hazrath ‘Isa (alaihis salaam) and the Holy Quran was revealed to our Nabi Hazrath Muhammad (sallal laahu alaihi wa sallam) .
The followers of these prophets altered these books (Tauraat,Zaboor and Injeel), added or extracted statements and,therefore changed the orders of Allah Ta’ala .
The Holy Quran is such a unique book that no one can make another like it .Even whole world tried together to make one,they would not be able to.
The Holy Quran is complete with all the knowledge and every aspects is enlightened .it is the same now as was fourteen hundred years as it was when it was revealed , and will always remain the same.
Those who say that someone has altered or increased or decreased The Holy Quran or that the true Quran is kept by the imaam of the unseen, then they are Kaafirs .The Holy Quran that we have today is the true Quran.
It is necessary for all to bring faith on this Holy Quran. There will not come a new Prophet or a new Book. Those who believe against this are not Muslims.
