The first Wahi (divine revelation) in Islam was sent to Prophet Muhammad (PBUH) during the month of Rajab-ul-Murajab. This event is highly significant as it marked the beginning of his Prophethood and the start of the Quranic revelation.

According to Islamic history, the Prophet (PBUH) used to spend time in deep meditation and worship in the Cave of Hira, which is near Makkah. During one of these spiritual retreats, in the month of Rajab, the angel Jibbrail (A.S) appeared and revealed the first verses of Surah Al-Alaq.

This moment was a turning point in the history of Islam. It began the process of delivering Allah’s final message to humanity. Though the month of Ramadan is famous for Quranic revelations, the very first Wahi happened earlier in Rajab.

The month of Rajab is therefore considered one of the four sacred months in Islam, during which fighting is forbidden and acts of worship are encouraged. The descent of the first Wahi during this month emphasizes its spiritual importance.

Knowing the exact month of the first revelation helps Muslims connect deeply with their faith and the journey of the Prophet (PBUH). It is a common question in Islamic studies and exams because it highlights a crucial moment in Islamic history.

Thus, the correct answer is: Rajab-ul-Murajab. This fact is essential for anyone studying the life of the Prophet and the origins of Islam.
