First Night of Rajab
A number of rites have been reported to be advisably said or done at the first night in Rajab, which is a holy night. These rites are as follows:
It has been also reported that when his eyes fell on the new moon of Rajab, the Holy Prophet (صلى الله عليه وعلى آله وسلم) used to say the following:
Whoever receives the month of Rajab and bathes himself in the first, middle, and last of it, will be released from all of his sins to return as pure as the day of his birth.
Similarly, Salawat on Holy Prophet and their Progeny should be recited thirty times:
The reward of this prayer is that whoever offers it, will have all his sins forgiven and will return as sin-free as the day of his birth.
Imam Abu-Ja’far II (عليه السلام) is reported to have recommended saying this the following supplication at the first night of Rajab after the Isha’ Prayer:
You may then mention your requests.
Ali ibn Hadid has narrated that Imam Musa ibn Ja’far (عليه السلام) used to recite the following supplication while prostrating after the completion of the Night Prayer (Salat al-Layl):
Ibn Ashyam says: It is recommended to recite this supplication after offering the eight-unit salat al-Layl (Night Prayer) and before offering the three-unit salat al-witr. Immediately after offering this prayer, it is recommended to recite this supplication while sitting:
It is worth mentioning that our scholars have mentioned special prayers to be offered at each night in Rajab.
FIRST DAY OF RAJAB
The first day of Rajab is a holy day on which there are several rites to be advisably done:
The following invocation should be said thereafter:
Then, one should pass the hands over the face.
Other ten units of this prayer should be offered on the fifteenth (i.e. middle) of Rajab in the very aforementioned form. However, the following invocation should be added after the first one:
The last ten units of this prayer should be offered on the last day of Rajab in this very form; rather, the following invocation is added after the first one:
Then, one should pass the hands over the face and submit his requests.
This greatly beneficial prayer must not be neglected. However, Salman has another prayer, to be offered on this day, which consists of ten units in each of which Surah al-Fātiḥah should be recited once and Surah al-Tawḥīd three times. This prayer brings about a great reward; it achieves forgiveness of all sins, protects against the grave torture and the chastisement on the Resurrection Day, and saves from leprosy, elephantiasis, and pleurisy.
Sayyid Ibn Tawus has also mentioned, in his book of Iqbal al-A’mal, another prayer that is offered on the first of Rajab.
