عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَعَلَى آلِهِ وَسَلَّمَ قَالَ: ((قَالَ رَبُّنَا عَزَّ وَجَلَّ: الصِّيَامُ جُنَّةٌ يَسْتَجِنُّ بِهَا الْعَبْدُ مِنَ النَّارِ وَهُوَ لِي وَأَنَا أَجْزِي بِهِ))
Narrated by Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both), the Messenger of Allah (peace and blessings be upon him) said: Our Lord has said: Fasting is a shield by which a servant protects himself from Hell, and it is only for Me, and I alone will reward it.
