(20) باب فَضْلِ مَنْ أَنْفَقَ زَوْجَيْنِ فِي سَبِيلِ اللَّهِ عَزَّ وَجَلَّ .
Abu Hurairah used to narrate that the Messenger of Allah (ﷺ) said:
"Whoever spends on a pair (of things) in the cause of Allah, he will be called in Paradise: 'O slave of Allah, here is prosperity.' Whoever is one of those who pray, he will be called from the gate of Paradise. Whoever is one of those who participated in Jihad, he will be called from the gate of Paradise. Whoever is one of those who fast, he will be called from the gate of Ar-Rayyan." Abu Bakr As-Siddiq said: "O Messenger of Allah! No distress, or need will befall the one who is called from those gates. Will there be anyone who will be called from all these gates? The Messenger of Allah (ﷺ) said: "Yes, and I hope that you will be one of them."
