Hadith 2511822 - وَ قَالَ أَبُو اَلْحَسَنِ مُوسَى بْنُ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ : « رَجَبٌ شَهْرٌ عَظِيمٌ يُضَاعِفُ اَللَّهُ فِيهِ اَلْحَسَنَاتِ وَ يَمْحُو فِيهِ اَلسَّيِّئَاتِ مَنْ صَامَ يَوْماً مِنْ رَجَبٍ تَبَاعَدَتْ عَنْهُ اَلنَّارُ مَسِيرَةَ سَنَةٍ وَ مَنْ صَامَ ثَلاَثَةَ أَيَّامٍ وَجَبَتْ لَهُ اَلْجَنَّةُ ».
Hadith.1822 - Abu al-Hasan Imam Musa ibn Jafar Al-Kadhim (as) said:
"Rajab is a great month. In it, Allah (swt) multiplies good deeds and erases sins. Whoever fasts a day in Rajab, the Fire will be distanced from him by a journey of one year, and whoever fasts three days, Paradise becomes obligatory for him."
