Islam is a monotheistic and Abrahamic religion articulated by the Qur'an, a book considered by its adherents to be the verbatim word and by the teachings and normative example (called the Sunnah and composed of hadith) of Muhammad, considered by them to be the last prophet of God. An adherent of Islam is called a Muslim.

Hinduism is the dominant religion of the Indian subcontinent, particularly of India and Nepal, which consists of many diverse traditions. It includes Shaivism, Vaishnavism and Shaktism among numerous other traditions, and a wide spectrum of laws and prescriptions of "daily morality" based on karma, dharma, and societal norms. Hinduism is a categorisation of distinct intellectual or philosophical points of view, rather than a rigid, common set of beliefs.

The foundations of Christian theology are expressed in ecumenical creeds. These professions of faith state that Jesus suffered, died, was buried, and was resurrected from the dead in order to grant eternal life to those who believe in him and trust in him for the remission of their sins. The creeds further maintain that Jesus bodily ascended into heaven, where he reigns with God the Father..

Buddhism is a nontheistic religion that encompasses a variety of traditions, beliefs and practices largely based on teachings attributed to Siddhartha Gautama, who is commonly known as the Buddha, meaning "the awakened one". According to Buddhist tradition, the Buddha lived and taught in the eastern part of the Indian subcontinent sometime between the 6th and 4th centuries BCE. He is recognized by Buddhists as an awakened or enlightened teacher who shared his insights to help sentient beings end their suffering through the elimination of ignorance and craving by way of understanding and the seeing of dependent origination, with the ultimate goal of attainment of the sublime state of nirvana.

Adherents of Sikhism are known as Sikhs (students or disciples). According to Devinder Singh Chahal, "The word 'Sikhi' (commonly known as Gurmat) gave rise to the modern anglicized word 'Sikhism' for the modern world." Gurmat means literally 'wisdom of the Guru' in contrast to Manmat, or self-willed impulses.

The word Jainism is derived from a Sanskrit verb Jin which means to conquer. It refers to a battle with the passions and bodily pleasures that the jaina ascetics undertake. Those who win this battle are termed as Jina (conqueror). The term Jaina is therefore used to refer to laymen and ascetics of this tradition alike.

Largely due to such ethnolinguistic and cultural discrepancies, opinion has differed on whether animism refers to a broadly religious belief or to a full-fledged religion in its own right. The currently accepted definition of animism was only developed in the late 19th century by Sir Edward Tylor, who created it as "one of anthropology's earliest concepts, if not the first".

Ahmadi thought emphasizes the belief that Islam is the final dispensation for humanity as revealed to Muhammad and the necessity of restoring to it its true essence and pristine form, which had been lost through the centuries. Thus, Ahmadis view themselves as leading the revival and peaceful propagation of Islam.The Ahmadis were among the earliest Muslim communities to arrive in Britain and other Western countries.
