The Rewards & Punishments of Deeds · Hadith 224 (#Ḥadīth #3)

وَ بِهَذَا الْإِسْنَادِ قَالَ أَبُو الْحَسَنِ ع رَجَبٌ شَهْرٌ عَظِیمٌ یُضَاعِفُ اللَّهُ فِیهِ الْحَسَنَاتِ وَ یَمْحُو فِیهِ السَّیِّئَاتِ مَنْ صَامَ یَوْماً مِنْ رَجَبٍ تَبَاعَدَتْ عَنْهُ النَّارُ مَسِیرَهَ مِائَهِ سَنَهٍ وَ مَنْ صَامَ ثَلَاثَهَ أَیَّامٍ وَجَبَتْ لَهُ الْجَنَّهُ.

3. Imam Musa Kadhim says, “Rajab is a glorious month. Allah doubles good deeds and wipes the sins in this month. One who observes one fast in Rajab, Hell would go away from him to a distance of a year and Paradise would be made obligatory on one who fasts for three days.”
