عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ثَلَاثٌ كُلُّهُمْ حَقٌّ عَلَى اللَّهِ عَوْنُهُمْ الْمُجَاهِدُ فِي سَبِيلِ اللَّهِ وَالنَّاكِحُ الْمُسْتَعْفِفُ وَالْمُكَاتَبُ يُرِيدُ الْأَدَاءَ
Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: There are three persons whose help is a duty upon Allah: the one who strives in the way of Allah, the one who marries to preserve his chastity, and the slave who has a contract (of manumission) and intends to fulfill it.
