When is Rabi al-Awwal 2026?
Rabi al-Awwal 2026 begins on approximately Friday 14 August 2026, which corresponds to 1 Rabi al-Awwal 1448 AH in calculated Hijri calendars such as Hijri-Gregorian and AlAdhan. Because Islamic days start at sunset, the month actually enters on the evening of Thursday 13 August.
The month runs for 29 or 30 days, ending on approximately 11 September 2026, when Rabi al-Thani begins. As with every Hijri month, the exact start and end depend on the sighting of the new crescent moon, so dates can shift by a day between countries — and even between mosques in the same UK city.

What does Rabi al-Awwal mean?
Rabi al-Awwal (ربيع الأول) translates as "the first spring" — a name given in pre-Islamic Arabia when the month coincided with the spring grazing season. It is the third month of the Islamic Hijri calendar, arriving after Muharram and Safar, and followed by Rabi al-Thani ("the second spring").
Because the Hijri calendar is lunar and about 11 days shorter than the Gregorian year, the month moves through the seasons over time. In 2026 it falls in late summer for UK Muslims, roughly two months after the Islamic New Year in June.
Above all, it is known simply as the month of the Prophet ﷺ. The majority of scholars hold that Muhammad ﷺ was born in this month in Makkah, in the Year of the Elephant — approximately 570 CE — and it is this association that gives the month its special place in Muslim life.
What happened in Rabi al-Awwal?
Few Hijri months carry as much history. As Dr. Khairil Husaini Bin Jamil notes in his survey of the month for IslamiCity, "Rabiul Awwal presents us with mixed feelings whenever it arrives" — because it holds both the most joyful and the most sorrowful dates in the Islamic story.
The momentous events of the month, from the Prophet’s ﷺ birth to his passing.
The birth of the Prophet ﷺ is the event the month is best known for. But it is also the month in which the Prophet ﷺ completed the Hijrah, arriving in Madinah after the migration from Makkah. On the way he established Masjid Quba — the first mosque built in Islam — and shortly afterwards led the first Jumu'ah (Friday) congregational prayer.
It is also the month of his passing. The Prophet ﷺ died in Madinah in Rabi al-Awwal 11 AH at the age of 63 — according to many accounts on the 12th, the same date as his birth. Abu Bakr al-Siddiq was appointed the first caliph in the days that followed. This coincidence of birth and death gives the month a reflective, bittersweet character for many Muslims.
When is Mawlid al-Nabi 2026?
Mawlid al-Nabi 2026 falls on Tuesday 25 August, corresponding to 12 Rabi al-Awwal 1448 AH, subject to moon sighting (IslamicFinder). It commemorates the birth of the Prophet Muhammad ﷺ and is marked by hundreds of millions of Muslims worldwide with gatherings, salawat, Seerah study and charity.
The 12th is the most widely observed date, but not the only one: some historians place the birth on the 2nd, 8th, 9th or 10th of the month, and most Shia Muslims observe the 17th — 30 August in 2026. Observance itself also varies: many communities hold Mawlid celebrations, while others prefer to mark the month through extra worship and study alone.
We cover the date, history and scholarly perspectives in full in our dedicated Mawlid al-Nabi 2026 guide.
How do Muslims observe Rabi al-Awwal 2026?
There are no obligatory acts of worship specific to this month — no required fasting, and no prescribed rituals. Instead, Muslims traditionally use the month to draw closer to the Prophet ﷺ through voluntary devotion. Around 3.9 million Muslims live in England and Wales — 6.5% of the population, per the ONS 2021 Census — and UK mosques typically fill the month with Seerah lectures and Mawlid gatherings.
Common observances include:
- Sending salawat — increasing blessings and salutations upon the Prophet ﷺ throughout the month.
- Studying the Seerah — reading the Prophet's ﷺ biography, individually or in study circles.
- Fasting Mondays — a year-round Sunnah that takes on special meaning this month. Asked about fasting on Mondays, the Prophet ﷺ replied: "That is the day on which I was born and the day on which I received Revelation" (Sahih Muslim, via Riyad as-Salihin 1255).
- Giving charity — emulating the Prophet's ﷺ generosity through sadaqah and zakat.
- Reviving his character — scholars across all schools agree the best commemoration is embodying the Prophet's ﷺ mercy, honesty and compassion in daily life.
Why give charity in Rabi al-Awwal?
The Prophet ﷺ was described by his companions as the most generous of people. For many UK Muslims, the month of his birth is a natural time to give — especially sadaqah jariyah, ongoing charity that continues to benefit people (and continues to reward the giver) long after the donation is made.
At HNCO, a UK non-profit organisation, donations in this month most often go towards clean water projects and masjid construction in Pakistan — both classic forms of sadaqah jariyah, and both zakat-eligible.

Honour Rabi al-Awwal with charity that keeps giving — a water well, a masjid, or an ongoing forever donation.

Like every Hijri month, it begins with the new crescent moon. Two approaches exist side by side: Saudi Arabia's Umm al-Qura calendar fixes dates in advance by astronomical calculation, while many communities — including many UK mosques — wait for a verified local or regional sighting.
In practice this means the dates in this guide, drawn from calculated calendars such as AlAdhan's 1448 AH tables, may differ by a day from your mosque's announcement. When the precise date matters — for example, planning a Mawlid gathering — always confirm with your local mosque or Islamic authority.
Rabi al-Awwal 2026 — Frequently Asked Questions
When does Rabi al-Awwal 2026 start?
Rabi al-Awwal 2026 starts on approximately Friday 14 August 2026 (1 Rabi al-Awwal 1448 AH), entering from sunset on Thursday 13 August. The exact date depends on the sighting of the new crescent moon.
When is 12 Rabi al-Awwal in 2026?
12 Rabi al-Awwal 1448 AH is expected to fall on Tuesday 25 August 2026, subject to moon sighting. This is the date most Muslims observe as Mawlid al-Nabi, the birth of the Prophet Muhammad ﷺ.
Was the Prophet Muhammad ﷺ definitely born on 12 Rabi al-Awwal?
The majority view places his birth on the 12th of the month in the Year of the Elephant (approximately 570 CE), but historians have also proposed the 2nd, 8th, 9th, 10th and 17th of the month. The 12th remains the most widely observed date, while most Shia Muslims observe the 17th.
Is fasting required in Rabi al-Awwal?
No. There is no obligatory fasting this month. Many Muslims fast voluntarily on Mondays year-round, following the Prophet's ﷺ statement that Monday was the day of his birth and of the first revelation (Sahih Muslim).
Is celebrating Mawlid al-Nabi obligatory?
No. Marking the Mawlid is a matter of scholarly difference: many communities hold celebrations of gratitude, gatherings and salawat, while others prefer to honour the month through extra worship, Seerah study and charity alone. All agree that following the Prophet's ﷺ example is the heart of the matter.
Why do Rabi al-Awwal dates differ between countries?
Because the Islamic calendar is lunar. Saudi Arabia's Umm al-Qura calendar uses astronomical calculation, while many communities rely on local moon sighting — so the month can begin a day earlier or later depending on where you are and which method your mosque follows.
What is the best charity to give in Rabi al-Awwal?
Any sincere charity is rewarded, but sadaqah jariyah — ongoing charity such as a water well or a masjid — is especially fitting in the Prophet's ﷺ month, as its benefit and reward continue for years. HNCO water wells in Pakistan start from £150, and all water projects are zakat-eligible.
What month comes after Rabi al-Awwal 2026?
Rabi al-Thani ("the second spring"), the fourth month of the Islamic calendar, begins on approximately 12 September 2026, subject to moon sighting.
