'Lailatul Qadr' (Arabic: لیلة القدر‎) (also known as Shab-e-Qadr), the Night of Destiny, Night of Power, Night of Value, the Night of Decree or Night of Measures, is the anniversary of two very important dates in Islam that occurred in the month of Ramadan. It is the anniversary of the night Muslims believe the first verses of the Quran were revealed to the Islamic prophet Muhammad.

Lailatul Qadr' is the night that the Quran was revealed. All Muslims believe that revelation of the Quran occurred in two phases, with the first phase being the revelation in its entirety on Lailatul Qadr' to Gabriel (Jibril in Arabic) in the lowest heaven, and then the subsequent verse-by-verse revelation to Muhammad by the angel Gabriel (Jibril in Arabic). The revelation started in 610 CE at the Hira cave on Mount Nur in Mecca.The first Surah that was revealed was Surah Al-Alaq which is also commonly referred to as Surah Al-Iqra. Muslims should worship as much as they can on this night. This night is also believed to be the night when God decides the destiny of everyone.

Before becoming a public speaker, he trained as a doctor. He has written two booklets on Islam and comparative religion. He is regarded as an exponent of the Salafi ideology; he places a strong emphasis on individual scholarship and the rejection of "blind Taqlid", which has led him to repudiate the relevance of sectarian or Madh'hab designations, all the while reaffirming their importance.

Later he enrolled at Kishinchand Chellaram College, before studying medicine at Topiwala National Medical College and Nair Hospital and later the University of Mumbai, where he obtained a Bachelor of Medicine and Surgery (MBBS).

Shaykh Ahmad ibn Zayn al-Dín ibn Ibráhím al-Ahsá'í (Arabic: شيخ أحمد بن زين الدين بن إبراهيم الأحسائي‎) was (1753–1826) was the founder of a 19th century Shi`i school in the Persian and Ottoman empires, whose followers are known as Shaykhís.

He was a native of the Al-Ahsa region (Eastern Arabian Peninsula), educated in Bahrain and the theological centers of Najaf and Karbala in Iraq. Spending the last twenty years of his life in Iran, he received the protection and patronage of princes of the Qajar dynasty.

Little is documented about the early life of Shaykh Ahmad, except that he was born in Ahsa, in the northeast of the Arabian peninsula, to a Shi'i family of Sunni origin in either the year 1166 A.H. (1753 C.E.), or 1157 A.H. (1744 C.E.). Nabíl-i-A`zam, a Baha'i historian, documents his spiritual awakening in his book The Dawn-Breakers as follows:

While it is unclear how much of Nabil's interpretation is consistent with Shaykh Ahmad's true feelings, the underlying motivations for reform, and ultimately for messianic expectation, become somewhat clearer.
