Rabi' al-Awwal

The word "Rabi" means "spring" and Al-awwal means "the first" in the Arabic language, so "Rabi' al-awwal" means "the first spring" in Arabic. The name seems to have to do with the celebratory events in the month, as spring marks the end of winter (a symbol of sadness) and consequently the start of happiness. As the Islamic calendar is a purely lunar calendar, the month naturally rotates over solar years, so Rabīʽ al-awwal can fall in spring or any other season. Therefore, the month cannot be related to the actual season of spring.[3]

Although historians and scholars disagree on the exact date of Muhammad's birth,[4] it is celebrated by some Muslims on the 12th or 17th of Rabi' al-awwal.

Mawlid is done across the globe by some Muslims. Some muslims do not partake whatsoever as they believe it to be an innovation.

The essence of the Mawlid is from the Sunnah. The sahaba would congregate specifically to thank Allah for blessing them with the prophet, distribute food, read poetry about the prophet as done by Hassan Ibn Thabit, speak about the life and birth of the Prophet and other praiseworthy acts which is what is carried out in Mawlid gatherings today. The Prophet ‎صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّم would fast on Mondays as it was the day he ‎صَلَّى اللّٰهُ عَلَيْهِ وَسَلَّم was born (Sahih Muslim)

Although a lot of Muslims make an extra effort in the month of Rabi Ul Awwal, mawlid can be done at any day and time of the year. It is done by all Muslims everyday without realising - simply praising the Prophet or speaking about the seerah (life of prophet) can be a form of mawlid.

In many countries, a procession is also conducted on the night and day of the 12th or 17th of Rabi' al-awwal. On these occasions, sweets and drinks are distributed widely from home to home and the general public. In some areas, Muslims also exchange gifts. This (birthday celebration/procession) is an innovation, not practiced nor recommended by the Prophet or his Companions. In fact the Prophet is said to have disapproved of festival-like celebrations other than the two Eids (narration: Sunan Abī Dāwūd 1134).

The Islamic calendar is a purely lunar calendar, and months begin when the first crescent of a new moon is sighted. Since the Islamic lunar year is 11 to 12 days shorter than the solar year, Rabī‘ al-Awwal migrates throughout the seasons. The estimated start and end dates for Rabī‘ al-Awwal are as follows (based on the Umm al-Qura calendar of Saudi Arabia[5]):

• 01 Rabī‘ al-Awwal 897 AH, the fall of the Emirate of Granada, the final Muslim kingdom of al-Andalus
• 08 Rabī‘ al-Awwal, death of Imam Hassan Al-Askari Twelver Imām, Hasan al-‘Askarī (see: Chup Tazia)
