According to search-discovered classical Islamic scholarship, the scripture 'given to David' as mentioned in Quran 4:163 is the Zabur, unanimously identified by commentators as the Psalms. The tafsir of Ibn Kathir on this verse emphasizes that this revelation places Prophet David (Dawud) in the same esteemed chain of prophethood as Noah, Abraham, Moses, and Jesus, affirming the unity of the divine message. Al-Qurtubi further clarifies that the Zabur, consisting of 150 chapters, was not a book of new laws but was filled with wisdom, exhortations, and praises of God. The Arabic root of Zabur, z-b-r, meaning 'to write' or 'inscribe', points to its status as a written revelation. The synthesis of these scholarly views, grounded in Quran 4:163, establishes the Zabur as a significant book of divine wisdom and praise, revealed to Prophet David as part of the continuous guidance sent to humanity.
