Surah 29:6
"Whoever struggles, struggles only for himself. Surely God is indeed wealthy beyond the worlds."
29.6 – Whoever struggles, struggles only for himself
The uses of the Arabic verb jāhada (“to struggle”) in this sūra offer a chance to study its meaning when the context is not a battle scene (see also v. 8 and the comments at v. 69).
