Narrated by:Narrated Abu Hurairah:
That the Messenger of Allah (ﷺ) said: "There are three for whom it is a right upon Allah to help him: The Mujahid in the cause of Allah, the Mukatab who intends to fulfill (the Kitabah), and the one getting married who intends chastity." [Abu 'Eisa said:] This Hadith is Hasan.
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا اللَّيْثُ، عَنِ ابْنِ عَجْلاَنَ، عَنْ سَعِيدٍ الْمَقْبُرِيِّ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ثَلاَثَةٌ حَقٌّ عَلَى اللَّهِ عَوْنُهُمُ الْمُجَاهِدُ فِي سَبِيلِ اللَّهِ وَالْمُكَاتَبُ الَّذِي يُرِيدُ الأَدَاءَ وَالنَّاكِحُ الَّذِي يُرِيدُ الْعَفَافَ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ .
