Abrogate of relevation is a right of allah

AL-BAQARA (THE COW) : 106-113

2:106. None of Our revelations do We abrogate or cause to be forgotten, but We substitute something better or similar: Knowest thou not that Allah Hath power over all things?
2:107. Knowest thou not that to Allah belongeth the dominion of the heavens and the earth? And besides Him ye have neither patron nor helper.
2:108. Would ye question your Messenger as Moses was questioned of old? but whoever changeth from Faith to Unbelief, Hath strayed without doubt from the even way.

2:109. Quite a number of the People of the Book wish they could Turn you (people) back to infidelity after ye have believed, from selfish envy, after the Truth hath become Manifest unto them: But forgive and overlook, Till Allah accomplish Hiurpose; for Allah Hath power over all things.
2:110. And be steadfast in prayer and regular in charity: And whatever good ye send forth for your souls before you, ye shall find it with Allah: for Allah sees Well all that ye do.

2:111. And they say: "None shall enter Paradise unless he be a Jew or a Christian." Those are their (vain) desires. Say: "Produce your proof if ye are truthful."
2:112. Nay,-whoever submits His whole self to Allah and is a doer of good,- He will get his reward with his Lord; on such shall be no fear, nor shall they grieve.
2:113. The Jews say: "The Christians have naught (to stand) upon; and the Christians say: "The Jews have naught (To stand) upon." Yet they (Profess to) study the (same) Book. Like unto their word is what those say who know not; but Allah will judge between them in their quarrel on the Day of Judgment.
