حَدَّثَنَا النُّفَيْلِيُّ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ صَفْوَانَ بْنِ سُلَيْمٍ، وَسَعْدِ بْنِ سَعِيدٍ، عَنْ عُمَرَ بْنِ ثَابِتٍ الأَنْصَارِيِّ، عَنْ أَبِي أَيُّوبَ، صَاحِبِ النَّبِيِّ صلى الله عليه وسلم عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ مَنْ صَامَ رَمَضَانَ ثُمَّ أَتْبَعَهُ بِسِتٍّ مِنْ شَوَّالٍ فَكَأَنَّمَا صَامَ الدَّهْرَ ‏"‏ ‏.‏

Comment

Hadith Text & Reference

The Prophet (ﷺ) said: "If anyone fasts during Ramadan, then follows it with six days in Shawwal, it will be like a perpetual fast."

Reference: Sunan Abi Dawud 2433 | Book: Fasting (Kitab Al-Siyam)

Meaning & Significance

This hadith establishes the immense reward for fasting six days in Shawwal following Ramadan. The phrase "like a perpetual fast" means the reward is equivalent to fasting the entire year, as each good deed is multiplied tenfold: Ramadan (30 days) × 10 = 300 days, plus Shawwal's six days × 10 = 60 days, totaling 360 days—nearly a full year.

Juridical Ruling

The majority of scholars consider these six fasts to be a highly recommended Sunnah (mustahabb), not obligatory. They may be observed consecutively or separately throughout Shawwal, though immediate observance after Eid is preferable to avoid negligence.

Spiritual Wisdom

This practice bridges Ramadan's spiritual momentum into the rest of the year, maintaining taqwa (God-consciousness). It demonstrates gratitude for Ramadan's blessings, as good deeds following major acts of worship signify acceptance. The "perpetual fast" metaphor reflects Allah's boundless mercy in multiplying rewards for minimal effort.

Practical Notes

One must complete the Ramadan fast (making up any missed days first) before these voluntary fasts. Women with missed Ramadan days should prioritize making up obligatory fasts over Shawwal fasts. The intention (niyyah) for these fasts should be made during the night or before dawn.
