Re: fasting in the month rajab , shaban, n shawal.
The story seems doubtful. It’d be nice if you could provide references for the material that you post.
Rajab is indeed one of the sacred months, but I haven’t yet come across material that recommends fasting in Rajab.
Here’s a bit on Rajab that relates to this thread:
Rajab is a sacred month
The Sacred months have a special status, which applies also to Rajab because it is one of these sacred months. Allaah says (interpretation of the meaning):
“O you who believe! Violate not the sanctity of the Symbols of Allaah, nor of the Sacred Month…” [al-Maa’idah 5:2]
This means: do not violate their sanctity which Allaah has commanded you to respect and forbidden you to violate, for this prohibition includes both vile deeds and vile beliefs.
Allaah says (interpretation of the meaning):
“so wrong not yourselves therein…” [al-Tawbah 9:36] meaning, in the Sacred Months. The pronoun here [translated here as “therein”] refers to these four sacred months, as stated by the Imaam of the Mufassireen, Ibn Jareer al-Tabari (may Allaah have mercy on him).
So we should pay attention to the sanctity of these four months, because Allaah has singled them out for a special status and has forbidden us to commit sins out of respect for their sanctity, for sins committed at this time are even worse, because of the sanctity of the time which Allaah has made sacred. Hence in the aayah quoted above, Allaah has forbidden us to wrong ourselves even though this – i.e., wronging ourselves, which includes committing sins – is forbidden during all the months of the year.
Fasting in Rajab
There is no saheeh report from the Prophet (peace and blessings of Allaah be upon him) or from the Sahaabah to indicate that there is any particular virtue in fasting during Rajab.
The fasting that is prescribed in Rajab is the same as that prescribed in other months, namely fasting on Mondays and Thursdays, and the three days of al-Beed, fasting alternate days, and fasting Sirar al-Shahr. Some of the scholars said that Sirar al-Shahr refers to the beginning of the month; others said that it refers to the middle or end of the month. ‘Umar (may Allaah be pleased with him) used to forbid fasting in Rajab because it involved resemblance to the Jaahiliyyah. It was reported that Kharashah ibn al-Harr said: I saw ‘Umar smacking the hands of those who fasted in Rajab until they reached out for food, and he was saying, This is a month which was venerated in the Jaahiliyyah. (al-Irwaa’, 957; al-Albaani said: it is saheeh).
Imaam Ibn al-Qayyim said: the Prophet (peace and blessings of Allaah be upon him) did not fast for three consecutive months (i.e., Rajab, Sha’baan and Ramadaan) as some people do, and he never fasted Rajab at all, nor did he encourage people to fast this month.
Al-Haafiz ibn Hajar said in Tabayyun al-‘Ajab bimaa wurida fi Fadl Rajab:
No saheeh hadeeth that may be used as evidence has been narrated concerning the virtues of the month of Rajab or fasting this month or fasting in any specific part of it, or observing Qiyaam al-Layl specifically during this month. Imaam Abu Ismaa’eel al-Harawi al-Haafiz has already stated this before me, and we have narrated this from others also.
In Fataawa al-Lajnah al-Daa’imah it states: with regard to fasting specifically in Rajab, we do not know of any basis in Sharee’ah for doing that.
