"There are three, all of whom have a promise of help from Allah: 'The Mujahid who strives in the cause of Allah, the Mighty and Sublime; the man who gets married, seeking to keep himself chaste; and the slave who has a contract of manumission and wants to buy his freedom.'" (Using translation from Nasāʾī 3120)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «ثَلَاثَةٌ حَقٌّ عَلَى اللهِ ﷻ عَوْنُهُمْ الْمُكَاتَبُ الَّذِي يُرِيدُ الْأَدَاءَ وَالنَّاكِحُ الَّذِي يُرِيدُ الْعَفَافَ وَالْمُجَاهِدُ فِي سَبِيلِ اللهِ»
