Surah Al-Isra' (The Night Journey), Verse 19

وَمَنْ اَرَادَ الْاٰخِرَةَ وَسَعٰی لَهَا سَعْیَهَا وَهُوَ مُؤْمِنٌ فَاُولٰٓىِٕكَ كَانَ سَعْیُهُمْ مَّشْكُوْرًا ۟

Wa man araadal Aakhirata wa sa'aa lahaa sa'yahaa wa huwa mu'minun fa ulaaa'ika kaana sa'yuhum mashkooraa

“Those who do wish for the (things of) the Hereafter, and strive therefor with all due striving, and have Faith,- they are the ones whose striving is acceptable (to Allah).”

Quran 17:19 (Yusuf Ali Translation)
