Children of Israel Cursed Upon Tongue of David (5:78)

 بِسۡمِ اللّٰہِ الرَّحۡمٰنِ الرَّحِیۡمِ

In the Name of Allah, the Rahman, the Merciful

الصلاة والسلام عليك يا سيدي يا رسول الله

Salutations and peace upon you, my master, Apostle of Allah

Allah, holy and exalted is He, says:

لُعِنَ الَّذِیۡنَ کَفَرُوۡا مِنۡۢ بَنِیۡۤ اِسۡرَآءِیۡلَ عَلٰی لِسَانِ دَاوٗدَ وَعِیۡسَی ابۡنِ مَرۡیَمَ ؕ ذٰلِکَ بِمَا عَصَوۡا وَّکَانُوۡا یَعۡتَدُوۡنَ

Cursed were those who disbelieved from the children of Israel upon the tongue of David and Jesus son of Mary. That is because they disobeyed and used to transgress

(Surah 5, Ayah 78)

As for King David, refer to Psalm 37 for his curse upon the Israelites: "And they that be cursed of him shall be cut off" (Psalm 37:22).

Psalm 37 is special for it is quoted elsewhere in the Holy Quran:

وَلَقَدۡ کَتَبۡنَا فِی الزَّبُوۡرِ مِنۡۢ بَعۡدِ الذِّکۡرِ اَنَّ الۡاَرۡضَ یَرِثُہَا عِبَادِیَ الصّٰلِحُوۡنَ

And We have written in the Zabur from after the Reminder that the Earth—it shall be inherited by My righteous servants

(Surah 21, Ayah 105)

This is clearly a reference to "but those that wait upon the LORD, they shall inherit the earth" (Psalm 37:9), "But the meek shall inherit the earth" (Psalm 37:11), "For such as be blessed of him shall inherit the earth" (Psalm 37:22), "the righteous shall inherit the land" (Psalm 37:29). It is particularly this Psalm that I have quoted last that is being directly cited in the Holy Quran

צַדִּיקִ֥ים יִֽירְשׁוּ־אָ֑רֶץ

Saddiqim yireshu ares

The righteous will inherit the land

From this we can reasonably conclude that Psalm 37 is truly a Psalm of David and an original inspiration to King David by God Himself.

Elsewhere, David expresses his anger and resentment and invokes God against his enemies: "Fight against them that fight against me" (Psalm 35:1), "Let them be confounded and put to shame that seek after my soul: let them be turned back and brought to confusion that devise my hurt. Let them be as chaff before the wind: and let the angel of the Lord chase them. Let their way be dark and slippery: and let the angel of the Lord persecute them. For without cause have they hid for me their net in a pit, which without cause they have digged for my soul. Let destruction come upon him at unawares; and let his net that he hath hid catch himself: into that very destruction let him fall" (Psalm 35:4-8), "Let them be ashamed and brought to confusion together that rejoice at mine hurt: let them be clothed with shame and dishonour that magnify themselves against me" (Psalm 35:26), "Destroy, O Lord, and divide their tongues" (Psalm 55:9), "Let death seize upon them, and let them go down quick into hell: for wickedness is in their dwellings, and among them" (Psalm 55:15), "Pour out thine indignation upon them, and let thy wrathful anger take hold of them. Let their habitation be desolate; and let none dwell in their tents" (Psalm 69:24-25), "Add iniquity unto their iniquity: and let them not come into thy righteousness. Let them be blotted out of the book of the living, and not be written with the righteous" (Psalm 69:27-28), "Let them be confounded and consumed that are adversaries to my soul; let them be covered with reproach and dishonour that seek my hurt" (Psalm 71:13), "Let mine adversaries be clothed with shame, and let them cover themselves with their own confusion, as with a mantle" (Psalm 109:29). This is but a glimpse into the Psalms of David in which he invokes God against his enemies who are his own people, the Israelites that troubled him and falsely accused him, conspired against him or sought to kill him. All these Psalms in which David cried out to God to pour out His wrath against these enemies have been summarized in the Quran with the words "Cursed were those who disbelieved from the Children of Israel upon the tongue of David".
