 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.”
