Question: What is the ruling on fasting six days of Shawwal? Is it Waajib (obligatory)?
Answer: Praise be to Allah.
Fasting six days of Shawwal after the obligatory fast of Ramadhan is Sunnah Mustahabbah, not Waajib. It is recommended for the Muslim to fast six days of Shawwal, and in this there is great virtue and an immense reward. Whoever fasts these six days will have recorded for him a reward as if he had fasted a whole year, as was reported in a saheeh hadeeth from the Prophet (peace and blessings of Allah be upon him). Abu Ayyoob (may Allah be pleased with him) reported that the Messenger of Allah (peace and blessings of Allah be upon him) said: โWhoever fasts Ramadhan and follows it with six days of Shawwal, it will be as if he fasted for a lifetime.โ
(Narrated by Muslim, Abu Dawood, al-Tirmidhi, al-Nisaaโi and Ibn Majah).
The Prophet (peace and blessings of Allah be upon him) explained this when he said: โWhoever fasts for six days after (Eid) al-Fitr has completed the year: (whoever does a good deed (hasanah) will have ten hasanah like it).โ According to another report: โAllah has made for each hasanah ten like it, so a month is like fasting ten months, and fasting six days completes the year.โ
(al-Nisaaโi and Ibn Majah. See also Saheeh al-Targheeb waโl-Tarheeb, 1/421). It was also narrated by Ibn Khuzaymah with the wording: โFasting for the month of Ramadhan brings the reward of ten like it, and fasting for six days brings the reward of two months, and that is the fasting of the whole year.โ
The Hanbali and Shaafaโi fuqahaโ explained that fasting six days of Shawwal after fasting Ramadhan makes it as if one has fasted for an entire year of obligatory fasts, because the multiplication of the reward applies even to naafil fasts, because each hasanah brings the reward of ten like it.
Another of the important benefits of fasting six days of Shawwal is that is makes up for any shortfall in a person’s obligatory Ramadhan fasts, because no one is free of shortcomings or sins that have a negative effect on his fasting. On the Day of Resurrection, some of his naafil deeds will be taken to make up the shortcomings in his obligatory deeds, as the Prophet (peace and blessings of Allah be upon him) said: โThe first thing for which people will be brought to account on the Day of Resurrection will be their salaah (prayer). Our Lord, may He be glorified and exalted, will say to His angels โ although He knows best โ โLook at the salaah of My slave, whether it is complete or incomplete.โ If it is perfect, it will be recorded as perfect, and if something is lacking, He will say, โLook and see whether My slave did any voluntary (naafil) prayers.โ If he did some voluntary prayers, [Allah] will say, Complete the obligatory actions of My slave from his voluntary actions.โ Then all his actions will be dealt with in a similar manner.โ
(Narrated by Abu Dawood).
And Allaah knows best.
