Before addressing this topic of abrogation, it is essential to state the following: Allah says in the glorious Qur’an:” We have, without doubt, sent down the Message; and We will assuredly guard it (from corruption).(Al-Hijr 15:9)

Thus, the Qur’an is the pure word of Allah. Not one word therein is not divine. Not a single word has been deleted from its text. The Book has been handed down to our age in its complete and original form since the time of Prophet Muhammad, peace and blessings be upon him. From the time the Book began to be revealed, the Prophet, peace and blessings be upon him, had dictated its text to the scribes. Whenever some Divine Message was revealed, the Prophet would call a scribe and dictate its words to him. The written text was then read out to the Prophet, peace and blessings be upon him, who, having satisfied himself that the scribe had committed no error of recording, would put the manuscript in safe custody.

As far as the issue of abrogation in the Qur’an is concerned, it has been a subject of disagreement among scholars. One of the considered opinions is that there is no cancellation or abrogation but there was always revocation or progression in setting up legal rulings.
Dr. Sano Koutoub Moustapha, professor of Fiqh and its Principles, International Islamic University, Malaysia, states: “The word abrogation is a translation of the word “naskh” which means revocation and replacement of a legal ruling with another legal ruling. It does not mean cancellation or amendment in the English sense.
However, this issue has been a subject of disagreement among scholars. I am of the opinion that there is no cancellation or abrogation but there was always revocation or progression in setting up legal rulings. In other words, the Qur’an was revealed to the Prophet (peace and blessings be upon him) in a gradual manner, so as to enable the people to have a better understanding of its meanings and teachings. This is stated in the Qur’an, Allah says what means: “And (it is) a Qur’an that We have divided, that you may recite it unto mankind at intervals, and We have revealed it by (successive) revelation.” (Al-‘Isra’: 106)
However, you should not bother your mind with this view or comment which claims that few verses have been abrogated. Do continue to read and study the Qur’an. Certainly, there is no doubt that what is in the Mus-haf (printed copy of the Qur’an) today is considered the Qur’an.”
