(20) باب مَا جَاءَ فِي الْمُجَاهِدِ وَالنَّاكِحِ وَالْمُكَاتَبِ وَعَوْنِ اللَّهِ إِيَّاهُمْ
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.
