حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ لاَ تَقَدَّمُوا صَوْمَ رَمَضَانَ بِيَوْمٍ وَلاَ يَوْمَيْنِ إِلاَّ أَنْ يَكُونَ صَوْمًا يَصُومُهُ رَجُلٌ فَلْيَصُمْ ذَلِكَ الصَّوْمَ ‏"‏ ‏.‏

Hadith Text & Reference

The Messenger of Allah (ﷺ) said: "Do not fast one day or two days just before Ramadan, except in the case of a man who has been in the habit of observing the particular fast, for he may fast on that day."

Prohibition Explained

This prohibition serves to create a clear distinction between voluntary fasting and the obligatory fast of Ramadan. By refraining from fasting immediately before Ramadan, we ensure that the sacred month begins with renewed spiritual energy and does not become mixed with voluntary acts that might cause exhaustion.

Scholars explain that this prohibition applies specifically to the day or two immediately preceding Ramadan, known as the "Day of Doubt" (Yawm al-Shakk), when there is uncertainty about the moon sighting.

Exception for Habitual Fasting

The exception applies to one who has an established pattern of fasting, such as someone who regularly fasts on Mondays and Thursdays, or one who observes the fast of Dawud (alternate days). If their habitual fasting day coincides with the day before Ramadan, they may continue their practice.

This demonstrates Islam's balance between maintaining recommended practices and avoiding potential harm to obligatory worship. The habitual faster is not considered to be anticipating Ramadan, but rather maintaining their consistent devotion.

Wisdom Behind the Ruling

Preventing physical and spiritual exhaustion before the month of obligatory fasting.

Distinguishing between voluntary and obligatory acts of worship to give each its proper due.

Following the Sunnah in preparing for Ramadan with proper spiritual and physical readiness.

Avoiding any resemblance to those who would add to the religion what does not belong to it.

Practical Application

Muslims should cease voluntary fasting 1-2 days before the expected beginning of Ramadan.

Those with established fasting habits may continue if their regular fast falls on these days.

The best preparation for Ramadan is through increased Quran recitation, remembrance of Allah, and seeking forgiveness rather than additional fasting.
