25:16
لَّهُمْ فِيهَا مَا يَشَآءُونَ خَـٰلِدِينَ ۚ كَانَ عَلَىٰ رَبِّكَ وَعْدًا مَّسْـُٔولًا
lahum fīhā mā yashāūna khālidīna kāna ʿalā rabbika waʿdan masūlan
There they will find everything they wish for, and there they will stay. [Prophet], this is a binding promise from your Lord.
For them there will be therein all that they desire, and they will abide (there forever). It is a promise binding upon your Lord that must be fulfilled.
