أَخْبَرَنَا عَمْرُو بْنُ عَوْنٍ ، حَدَّثَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ ، عَنْ وَاصِلٍ مَوْلَى أَبِي عُيَيْنَةَ، عَنْ بَشَّارِ بْنِ أَبِي سَيْفٍ ، عَنْ الْوَلِيدِ بْنِ عَبْدِ الرَّحْمَنِ ، عَنْ عِيَاضِ بْنِ غُطَيْفٍ ، عَنْ أَبِي عُبَيْدَةَ بْنِ الْجَرَّاحِ ، قَالَ : سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، يَقُولُ :" الصَّوْمُ جُنَّةٌ مَا لَمْ يَخْرِقْهَا ".
قَالَ أَبُو مُحَمَّد : يَعْنِي : بِالْغِيبَةِ

Amr bin Aoun told us, Khaled bin Abdullah told us, on the authority of Wasil the client of Abu Uyaynah, on the authority of Bashar bin Abi Saif, on the authority of Al-Walid Ibn Abd al-Rahman, on the authority of Iyad Ibn Ghaytif, on the authority of Abu Ubaidah Ibn al-Jarrah, who said: I heard the Messenger of God, may God bless him and grant him peace, saying: Fasting is a paradise as long as one does not break it.”
Abu Muhammad said: This means: by backbiting.
