The Prophet (pbuh) has been quoted to have said: "Rajab is a great month of Allah, unmatched by any other month in the respect and significance (accorded to it); war with the infidels during this month is prohibited; Verily, Rajab is Allah’s month, Sha’ban my month and Ramadhan the month of my Ummah; whosoever fasts a day in the month of Rajab will be granted the great reward of Ridhwan (an angel in heaven); the wrath of Allah shall be distanced and a door of the Hell shall be closed."

Acts for the Month

The month of Rajab has numerous prescribed acts and supplications. Most common is the supplication recommended to be recited daily by Imam Jafar al-Sadiq as follow:

يَا مَنْ أَرْجُوهُ لِكُلِّ خَيْرٍ ، وَ آمَنُ سَخَطَهُ عِنْدَ كُلِّ شَرٍّ ، يَا مَنْ يُعْطِي الْكَثِيرَ بِالْقَلِيلِ ، يَا مَنْ يُعْطِي مَنْ سَأَلَهُ ، يَا مَنْ يُعْطِي مَنْ لَمْ يَسْأَلْهُ وَ مَنْ لَمْ يَعْرِفْهُ تُحَنُّناً مِنْهُ وَ رَحْمَةً ، أَعْطِنِي بِمَسْأَلَتِي إِيَّاكَ جَمِيعَ خَيْرِ الدُّنْيَا ، وَ جَمِيعَ خَيْرِ الْآخِرَةِ ، وَ اصْرِفْ عَنِّي بِمَسْأَلَتِي إِيَّاكَ جَمِيعَ شَرِّ الدُّنْيَا وَ شَرِّ الْآخِرَةِ ، فَإِنَّهُ غَيْرُ مَنْقُوصٍ مَا أَعْطَيْتَ ، وَ زِدْنِي مِنْ فَضْلِكَ يَا كَرِيمُ يَا ذَا الْجَلَالِ وَ الْإِكْرَامِ ، يَا ذَا النَّعْمَاءِ وَ الْجُودِ ، يَا ذَا الْمَنِّ وَ الطَّوْلِ ، حَرِّمْ شَيْبَتِي عَلَى النَّارِ
