the prophet peace be upon him said :“Whoever fasts Ramadaan and follows it with six days of Shawwaal, it will be as if he fasted for a lifetime.” (Narrated by Muslim, Abu Dawood, al-Tirmidhi, al-Nisaa’i and Ibn Maajah).
Question:
What should a woman do first: fast the six recommended days of Shawwal ( Alayam Alsetta Albeed) or fast equivalent to the days she missed in Ramadan due to her monthly period?
Answer
Praise be to Allaah.
If she wants to earn the reward mentioned in the hadeeth of the Prophet (peace and blessings of Allaah be upon him), “Whoever fasts Ramadaan then follows it with six days of Shawwaal, it will be as if he fasted for a lifetime” (reported by Muslim, no. 1984), then she should complete her Ramadaan fasts first, then follow it with six days of Shawwaal, so that the hadeeth with be applicable to her too, and she will gain the reward mentioned in it.
As regards the matter of permissibility, it is permissible for her to delay making up her Ramadaan fasts, provided that she makes them up before the next Ramadaan comes along.

Question
Do the six days of Shawwaal have to be fasted consecutively?
Answer
Praise be to Allaah.
It is not a necessary condition that they should be fasted consecutively. If you fast them separately or consecutively, it is OK. The sooner you do them, the better, because Allaah says (interpretation of the meanings):
so compete in good deeds [al-Maaidah 5:48]
And march forth in the way (which leads to) forgiveness from your Lord [Aal Imran 3:133]
[Moosa peace be upon him said:] and I hastened to You, O my Lord, that You might be pleased [Ta-Ha 20:84]
And (you should hasten to fast these six days) because delaying may cause problems. This is the view of the Shaafa is and some of the Hanbalis, but it is OK if you do not hasten it and you delay it until the middle or end of the month.
Al-Nawawi (may Allaah have mercy on him) said:
Our companions said: it is mustahabb to fast six days of Shawwaal. Because of this hadeeth they said: it is mustahabb to fast these days consecutively at the beginning of Shawwaal, but if one separates them or delays them until after Shawwaal, this is permissible, because he will still be following the general guidelines of the hadeeth. We have no dispute regarding this matter, and this was also the view of Ahmad and Dawood.

Question
Will a person be rewarded if he combines three of the six days of Shawwaal with the Ayyaam al-Beed (Days 13,14,15 from every month)?
Answer
Praise be to Allaah.
I asked our Shaykh, ‘Abd al-‘Azeez ibn ‘Abd-Allaah ibn Baaz about this matter, and he replied that hopefully he will be rewarded for that, because it is true that he fasted the six days, and it is also true that he fasted the Ayyaam al-Beed, and the Bounty of Allaah is great indeed.
With regard to this particular matter, Shaykh Muhammad ibn Saalih al-‘Uthaymeen replied as follows:
“Yes, if he fasts six days of Shawwaal, he does not have to fast Ayyaam al-Beed during that month too, whether he fasted the six days at the same time as al-Ayyaam al-Beed (the 13th, 14th and 15th of the hijri month) or before them or after them, because it is true that he has fasted three days of the month. ‘Aa’ishah (may Allaah be pleased with her) said: ‘The Prophet (peace and blessings of Allaah be upon him) used to fast three days of every month, and he did not bother whether he fasted them at the beginning of the month or in the middle or at the end.”
This case is similar to that of Tahiyyat al-Masjid (prayer to “greet the mosque” upon entering),, which does not have to be done if one prays a regular prayer upon entering the mosque. So if you enter the mosque and pray a regular Sunnah prayer, you do not have to pray Tahiyyat al-masjid… And Allaah knows best.
