The word as it is recited in the Quran: Mahmoud Khalil Al-Hussary, Al-Bayyinah 98:8.
Khalid in Islam
Khalid ibn al-Walid embraced Islam shortly before the conquest of Mecca; at Muʾta, the Prophet ﷺ announced that the banner had been taken by “a sword among the swords of Allah” (al-Bukhari 4262), and he went on to lead the conquests of Iraq and Syria. Abu Ayyub al-Ansari, in whose house the Prophet ﷺ stayed in Medina, was named Khalid ibn Zayd. The Quran often uses khalid: “they will abide therein forever” (98:8).
Khalid is the active participle of khalada, “to remain, to last forever”: the root kh-l-d is that of permanence (khuld, khulud), and dar al-khuld, “the abode of eternity”, means the hereafter. The name expresses endurance and the wish for a name that lives on. The spelling Khaled reflects the usual pronunciation in Algeria, Tunisia and the Levant, while Khalid is the usual form in Morocco, the Gulf and in English.
Their reward with their Lord will be gardens of perpetual residence beneath which rivers flow, wherein they will abide forever, Allāh being pleased with them and they with Him. That is for whoever has feared his Lord.
And as for those who were [destined to be] prosperous, they will be in Paradise, abiding therein as long as the heavens and the earth endure, except what your Lord should will - a bestowal uninterrupted.
Say, "Shall I inform you of [something] better than that? For those who fear Allāh will be gardens in the presence of their Lord beneath which rivers flow, wherein they abide eternally, and purified spouses and approval from Allāh. And Allāh is Seeing [i.e., aware] of [His] servants -
And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally.
