وَالْمُجَاهِدُ مَنْ جَاهَدَ نَفْسَهُ فِي طَاعَةِ اللَّهِ.
Arabic word or phraseMeaning
وَالْمُجَاهِدُand the one who strives; here, in self-discipline
جَاهَدَ نَفْسَهُstrove against the self
فِي طَاعَةِ اللَّهِin obedience to Allah
جَاهَدَ is the action of striving. نَفْسَهُ is the previously studied “one’s own self.” فِي means “in,” طَاعَةِ means obedience, and اللَّهِ means Allah. Together they identify the purpose of the effort.
Teaching example: someone expects truthfulness to reduce personal gain but restrains that desire and speaks truthfully. Its purpose differs from working harder merely for greater earnings. The explanation emphasizes the importance of this striving; do not infer a ranking of every kind of striving from this short statement.
