Al-Kāfi|Volume 4|Book 2|Chapter 11
5ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ الله عَنْ آبَائِهِ (عَلَيْهِم السَّلاَم) قَالَ قَالَ رَسُولُ الله (صلَّى اللهُ عَلَيْهِ وَآلِه) مَا مِنْ عَبْدٍ صَالِحٍ يُشْتَمُ فَيَقُولُ إِنِّي صَائِمٌ سَلامٌ عَلَيْكَ لا أَشْتِمُكَ كَمَا شَتَمْتَنِي إِلاَّ قَالَ الرَّبُّ تَبَارَكَ وَتَعَالَى اسْتَجَارَ عَبْدِي بِالصَّوْمِ مِنْ شَرِّ عَبْدِي فَقَدْ أَجَرْتُهُ مِنَ النَّارِ.
5. Ali ibn Ibrahim has narrated from Harun ibn Muslim from Mas'adah ibn Sadaqah from Abu ‘Abdillah from his ancestors عليه السلام, he said: The Messenger of Allah صلى الله عليه وعلى آله وسلم said, "There is no righteous servant who is insulted and responds by saying, 'I am fasting, may peace be upon you, I do not insult you as you have insulted me,' except that the Lord, Blessed and Exalted, says, 'My servant has sought protection in fasting from the evil of My servant; thus, I grant him protection from the Fire.'"
