It has been narrated from Imam Jafar Sadiq; In the Name of Allah, the All-beneficent the All-merciful. You may say the following (supplicatory prayer) each day in Rajab; in mornings, evenings, and after each of the obligatory prayers:
يَا مَنْ ارْجُوهُ لِكُلِّ خَيْرٍ
Yaa Man Arjoohoo Likulli Khayr
O He Whom alone I hope for all good things
وآمَنُ سَخَطَهُ عِنْدَ كُلِّ شرٍّ
Wa-Aamanu Sakhatahoo `Inda Kulli Sharr
and Whose wrath I do not expect when I do wrong!
يَا مَنْ يُعْطِي ٱلْكَثِيرَ بِٱلْقَلِيلِ
Yaa Manyu`Til-Katheera Bil-Qaleel
O He Who recompenses the little deed with very much reward!
يَا مَنْ يُعْطَي مَنْ سَالَهُ
Yaa Manyu`Tee Man Sa-Alah
O He Who answers one who begs Him!
A`Tinee Bimasalatee Iyyaak Jamee`A Khayrid-Dunyaa
(Please do) give me, for I pray You, the whole welfare of this world
وَجَمِيعِ خَيْرِ ٱلآخِرَةِ
Wajamee`A Khayril-Aakhirah
and the whole welfare of the Next World
وَٱصْرِفْ عَنّي بِمَسْالَتي إِيَّاكَ
Wasrif `Annee Bimas-Alatee Iyyaak
and save me, for I pray You,
جَميعَ شَرِّ ٱلدُّنْيا وَشَرِّ ٱلآخِرَة
Jamee`A Sharrid-Dunyaa Washarril Aakhirah
the whole evil of this world and the Next World.
فَإِنَّهُ غَيْرُ مَنْقُوصٍ مَا اعْطَيْتَ
Fainnahoo Ghayru Manqoosin Maa A`Tayt Wazidnee
Verily, all that which You give is unblemished.
وَزِدْنِي مِنْ سَعَةِ فَضْلِكَ يَا كَرِيمُ
Min Fadhlika Yaa Kareem
(Please do) increase Your favors upon me, O All-generous!
The narrator then added that Imam al-Sadiq (`a) then grasped his beard with his left hand, while saying this supplicatory prayer, and moved ceaselessly the forefinger of his right hand. He then added:
يَا ذَاَ ٱلْجَلالِ وَٱلإِكْرَامِ
Yaa Dhaljalaali Walikraam
O Lord of Majesty and Honor!
يَا ذَاَ ٱلنَّعْمَاءِ وَٱلْجُودِ
Yadhanni`Maai Waljood
O Lord of bliss and magnanimity!
يَا ذَاَ ٱلْمَنِّ وَٱلطَّوْلِ
Yadhal-Manni Wattawl
O Lord of favor and munificence!
حَرِّمْ شَيْبَتِي عَلَىٰ ٱلنَّارِ
Harrim Shaybatee `Alan-Naar.
(Please do) rescue my white-hair beard from Hellfire.
