Al-Isra 19

وَمَنْ أَرَادَ ٱلْـَٔاخِرَةَ وَسَعَىٰ لَهَا سَعْيَهَا وَهُوَ مُؤْمِنٌ فَأُو۟لَـٰٓئِكَ كَانَ سَعْيُهُم مَّشْكُورًا

waman arāda l-ākhirata wasaʿā lahā saʿyahā wahuwa mu'minun fa-ulāika kāna saʿyuhum mashkūran

But whoever desires the Hereafter and exerts the effort due to it while he is a believer - it is those whose effort is ever appreciated [by Allāh].
