The Qur’an categorically says:
“Indeed, the religion in the sight of Allah is Islam……” [Qur’an 3:19]
In the above verse Allah states that there is no religion accepted with Him from any person, except Islam. Islam includes obeying all of the Messengers until Muhammad who finalized their commission, thus closing all paths to Allah except through Muhammad(pbuh) . Therefore, after Allah sent Prophet Muhammad , whoever meets Allah following a path other than Prophet Muhammad’s, it will not be accepted of him.
And then the verse continues as we read:
“…..And those who were given the Scripture did not differ except after knowledge had come to them – out of jealous animosity between themselves. And whoever disbelieves in the verses of Allah , then indeed, Allah is swift in [taking] account.”[Qur’an 3:19]
Allah then states that those who were given the scripture beforehand divided their religion after Allah sent the messengers and revealed books to them providing them necessary proofs not to do so. Allah said,’Those who were given the Scripture’ (i.e,Jews and Christians) did not differ except out of rivalry, after knowledge had come to them’, meaning, some of them wronged others. Therefore, they differed over the truth, out of envy, hatred and enmity for each other. This hatred made some of them defy those whom they hated even if they were correct. Allah then said, ‘And whoever disbelieves in the Ayat of Allah’, meaning, whoever rejects what Allah sent down in His Book, ‘then surely, Allah is Swift in reckoning’, means Allah will punish him for his rejection, reckon him for his denial, and torment him for defying His Book.
So, if anybody dies in the state of Disbelief shall taste the hell-fire.As we read in Qur’an:
And whoever desires other than Islam as religion – never will it be accepted from him, and he, in the Hereafter, will be among the losers.[Qur’an 3:85]
This shows that the religion of every Messenger of God, in every age and clime, was none other than Islam. Likewise, every Divine book, in whichever language it was revealed, and to whichever people it was addressed, contained the teachings of Islam. The various religions which have spread among mankind are distortions of this true, original religion, and are the result of tampering. Coveting privileges over and above those to which they were entitled, people altered the beliefs, principles and injunctions of the true religion in a manner conducive to their own interests.
Moreover in a Hadees Prophet Muhammad(pbuh) reported to have said:
It is narrated on the authority of Abu Huraira that the Messenger of Allah (ﷺ) observed:By Him in Whose hand is the life of Muhammad, he who amongst the community of Jews or Christians hears about me, but does not affirm his belief in that with which I have been sent and dies in this state (of disbelief), he shall be but one of the denizens of Hell-Fire.
[Sahih Muslim Hadees-153]
Therefore, after Allah sent Prophet Muhammad , whoever meets Allah following a path other than Prophet Muhammad’s, it will not be accepted of him.
Fleshing out the hadees’s theological implications, imam al-Nawawi said: ‘It contains [a proof] that all religions have now been abrogated by the prophethood of our Prophet ﷺ.Not only has the religion of Islam that the Prophet ﷺ was sent with superseded all previously revealed heavenly teachings, this last dispensation or “version” of Islam is a universal one too. As we read in Qur’an:
“Say, [O Muhammad], “O mankind, indeed I am the Messenger of Allah to you all…..” [Qur’an 7:158]
We have only sent you as a mercy to the worlds [Qur’an 21:107]
Also Prophet Muhammad(pbuh) claimed too that He was sent to mankind. As we read in a Hadees:
Narrated Jabir bin `Abdullah:The Prophet (ﷺ) said, “I have been given five things which were not given to anyone else before me.
-1. Allah made me victorious by awe, (by His frightening my enemies) for a distance of one month’s journey.
-2. The earth has been made for me (and for my followers) a place for praying and a thing to perform Tayammum, therefore anyone of my followers can pray wherever the time of a prayer is due.
-3. The booty has been made Halal (lawful) for me yet it was not lawful for anyone else before me.
-4. I have been given the right of intercession (on the Day of Resurrection).
-5. Every Prophet used to be sent to his nation only but I have been sent to all mankind.
[Sahih al-Bukhari Hadees-335]
Similarly Qur’an is the guidance for not only Muslims but entire mankind. As we read in Qur’an:
“Ramadhan is the (month) in which was sent down the Qur’an, as a guide to mankind,….” [Qur’an 2:185]
[Other Qur’an verse which says that Qur’an is the guidance for mankind are Qur’an 12:104, 81:27, 18:54, 4:174]
So that’s it folks!Whoever rejects Islam shall be amongst the losers.
