أَخْبَرَنِي عَمْرُو بْنُ عُثْمَانَ بْنِ سَعِيدِ بْنِ كَثِيرٍ، قَالَ حَدَّثَنَا أَبِي، عَنْ شُعَيْبٍ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي حُمَيْدُ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ ‏"‏ مَنْ أَنْفَقَ زَوْجَيْنِ مِنْ شَىْءٍ مِنَ الأَشْيَاءِ فِي سَبِيلِ اللَّهِ دُعِيَ مِنْ أَبْوَابِ الْجَنَّةِ يَا عَبْدَ اللَّهِ هَذَا خَيْرٌ لَكَ وَلِلْجَنَّةِ أَبْوَابٌ فَمَنْ كَانَ مِنْ أَهْلِ الصَّلاَةِ دُعِيَ مِنْ بَابِ الصَّلاَةِ وَمَنْ كَانَ مِنْ أَهْلِ الْجِهَادِ دُعِيَ مِنْ بَابِ الْجِهَادِ وَمَنْ كَانَ مِنْ أَهْلِ الصَّدَقَةِ دُعِيَ مِنْ بَابِ الصَّدَقَةِ وَمَنْ كَانَ مِنْ أَهْلِ الصِّيَامِ دُعِيَ مِنْ بَابِ الرَّيَّانِ ‏"‏ ‏.‏ قَالَ أَبُو بَكْرٍ هَلْ عَلَى مَنْ يُدْعَى مِنْ تِلْكَ الأَبْوَابِ مِنْ ضَرُورَةٍ فَهَلْ يُدْعَى مِنْهَا كُلِّهَا أَحَدٌ يَا رَسُولَ اللَّهِ قَالَ ‏"‏ نَعَمْ وَإِنِّي أَرْجُو أَنْ تَكُونَ مِنْهُمْ ‏"‏ ‏.‏ يَعْنِي أَبَا بَكْرٍ ‏.‏

Abu Hurairah said: "I heard the Messenger of Allah say" 'Whoever spends on a pair of things in the cause of Allah, he will be called from the gates of Paradise: O slave of Allah, this is good for you. Paradise had (several) gates. Whoever is one of the people of Salah, he will be called from the gate of prayer. Whoever is one of the people of Jihad, will be called from the gate of Jihad. Whoever is one of the people of charity will be called from the gate of charity. And whoever is one of the people of fasting will be called from the gate of Ar-Rayyan." Abu Bakr said: "Is there any need for anyone to be called from all of these gates? Will anyone be called from all of them, O Messenger of Allah?" He said: "Yes, and I hope that you will be among them." Translation Not Available
