Taṣdīq (تصديق)

Verification

In the Holy Quran:

وَمَا كَانَ هَٰذَا الْقُرْآنُ أَنْ يُفْتَرَىٰ مِنْ دُونِ اللَّهِ وَلَٰكِنْ تَصْدِيقَ الَّذِي بَيْنَ يَدَيْهِ وَتَفْصِيلَ الْكِتَابِ لَا رَيْبَ فِيهِ مِنْ رَبِّ الْعَالَمِينَ {37}

And this Quran was not such as could be forged by the ones besides Allah, but it is a Verification of those (Books) which were before it, and (it is) the detailed Book. There is no doubt it is from the Lord of the worlds [10:37]
