🌙 1. The Sacred Month of Allah (شهر الله المحرم)

The arrival of the new Islamic year is inaugurated by the sacred month of Muharram al-Haram (مُحَرَّم الحَرَام). In the Islamic tradition, Muharram holds a uniquely elevated sanctuary status as one of the four sanctified months ordained by Allah Almighty since the creation of the heavens and the earth.

In the Holy Qur’an, Allah explicitly warns against injustice and highlights the sanctity of these four months in Surah At-Tawbah:

The Prophet Muhammad ﷺ clarified these four months during his Farewell Pilgrimage (Hajjat al-Wada’) as being three consecutive months: Dhul-Qi’dah, Dhul-Hijjah, and Muharram, alongside the solitary month of Rajab (Sahih al-Bukhari 3197).

Furthermore, the Prophet ﷺ bestowed upon Muharram a title granted to no other month of the year: “The Sacred Month of Allah” (شهر الله المحرم). When asked which prayer is best after the obligatory prayers and which fast is greatest after Ramadan, he ﷺ replied:

🌾 2. The Historical Deliverance of Prophet Musa & The Day of Ashura

While every day of Muharram is blessed, the tenth day—known as Yawm ‘Ashura (يَوْمُ عَاشُورَاء) holds monumental historical and spiritual significance.

When the Prophet Muhammad ﷺ migrated from Makkah to Madinah in 622 CE, he found the Jewish community fasting on the 10th of Muharram. When he asked regarding the reason for their fast, they explained:

Thus, the Day of Ashura is a day of divine victory, the triumph of truth over tyranny, and a celebration of gratitude through voluntary fasting. To ensure you never miss the exact date regardless of your geographic location, you can calculate the upcoming milestone using the online Muharram Calendar and Ashura Calculator.

🥣 3. Virtues & Fiqh of Fasting: Expiation of Past Sins

The reward for fasting on the Day of Ashura is immense. The Prophet Muhammad ﷺ declared:

Why Combine the 9th of Muharram (Tasu’a) with Ashura?

Towards the culmination of his life, the companions informed the Messenger of Allah ﷺ that the 10th of Muharram was venerated by the People of the Book. Desiring to maintain a distinct Islamic identity and emphasize continuous devotion, the Prophet ﷺ expressed his definitive intention:

“If I remain alive until the coming year, I will certainly fast the ninth day as well (alongside the tenth).” (Sahih Muslim 1134)

Although the Prophet ﷺ passed away before the following Muharram, scholars across the four legal schools of Sunni jurisprudence (Hanafi, Maliki, Shafi’i, and Hanbali) unanimously agree that it is highly recommended (Mustahabb / Sunnah Mu’akkadah) to fast Tasu’a (9th) in conjunction with the Day of Ashura (10th).

Recommended Fasting Combinations

• Option 1 (Most Recommended — Sunnah): Fast the 9th and 10th of Muharram (Tasu’a & Ashura). This fulfills the Prophet’s explicit instruction.
• Option 2 (Alternate Pair): Fast the 10th and 11th of Muharram. If you missed fasting the 9th, classical jurists such as Imam Ahmad ibn Hanbal and Ibn al-Qayyim recommended pairing the 10th with the 11th to ensure two consecutive days are fasted.
• Option 3 (Maximum Reward — Triple Fast): Fast the 9th, 10th, and 11th of Muharram. This safeguards against differences in moon-sighting while maximizing reward in the sacred month.
• Option 4 (White Days — Ayyam al-Beed): Fast the 10th of Ashura, and then observe the Sunnah of fasting the 13th, 14th, and 15th of Muharram (the full moon days).

You can track your planned or completed fasts with an interactive progress circle using the Fasting Habit Planner on the Muharram Calendar Tool.

⚡ 4. Introducing the Universal Muharram Calendar Studio on RiazHub

Accurately coordinating Hijri dates with Gregorian business calendars often presents hurdles due to lunar visibility variations and regional sighting conventions. To solve this, RiazHub developed the Universal Muharram Calendar, Islamic New Year Ephemeris & Ashura Fasting Horology Studio.

Whether planning family fasting schedules or verifying historical dates, you can explore the full Muharram Ephemeris Studio here.

📊 5. Multi-Year Muharram & Ashura Ephemeris Projection (1445 AH – 1455 AH)

Because the Islamic lunar year is approximately 10 to 12 days shorter than the Gregorian solar year, the month of Muharram drifts backward through all four seasons over a 33-year cycle. Here is a quick reference mapping for the modern decade:

Note: Gregorian projections are based on astronomical calculations and the official Umm al-Qura calendar. Actual regional dates may shift by ±1 day depending on local crescent moon sightings. To calibrate for your specific country, use the interactive offset tuner on the RiazHub Muharram Calendar Tool.

❓ 7. Frequently Asked Questions (FAQ)

Can I fast only on the 10th of Muharram without the 9th?

Yes, according to the vast majority of Islamic scholars, fasting only on the 10th of Muharram (Ashura) is permissible and valid, and it fulfills the expiation of sins for the previous year. However, it is slightly disliked (Makruh Tanzihi) or contrary to the optimal Sunnah (Khilaf al-Awla) to isolate the 10th without fasting a day before (9th) or after (11th) to distinguish the practice.

What types of sins are forgiven by fasting on Ashura?

Scholars such as Imam an-Nawawi clarify that fasting on Ashura expiates all minor sins (as-sagha’ir). Major sins (al-kaba’ir) require sincere repentance (Tawbah), cessation of the wrongdoing, remorse, and restoring rights to aggrieved parties if applicable.

Can I combine the intention of making up missed Ramadan fasts with Ashura?

Yes, according to many contemporary scholars, if a person fasts on the Day of Ashura with the primary intention of making up an obligatory missed Ramadan fast (Qada’), they fulfill their obligation while also receiving the divine reward for fasting on Ashura by the grace of Allah.
