Ayah or Aayah (Arabic: آية āyah, plural: ayat or ayaat آيات āyāt) is the Arabic word for evidence or sign:

"These are the Ayat (proofs, evidences, verses, lessons, revelations, etc.) of Allah, which We recite to you (O Muhammad SAW) with truth. Then in which speech after Allah and His Ayat will they believe?" (Surat Al-Jathiya 45:6, Mohsin Khan translation of the Qur'an)

The word is usually used to refer to the smallest unit of the Qur'an, usually called 'verses' or 'signs' in English translations of the Qur'an. Muslims believe that each ayah of the Qur'an is a sign from God.

Chapters in the Qur'an, called suras in Arabic, are made up of several ayat, although suras vary greatly in length, ranging from 3 to 286 ayat. Within a long sura, ayat may be further divided into thematic sequences or passages.

A common myth persists that the number of ayat in the Qur'an is 6,666. In fact, the total number of ayat in all suras is 6,236; the number varies if the bismillahs are counted separately.

The verse number is written in a symbol at the end of each verse. This symbol is ۝, end of ayah. Its Unicode number is U+06DD.

Ahmed Hoosen Deedat (Arabic: احمد حسين ديدات; 1 July 1918 – 8 August 2005) was a South African writer and public speaker of Indian descent. He was best known as a Muslim missionary who held numerous inter-religious public debates with evangelical Christians, as well as video lectures, most of which centred around Islam, Christianity and the Bible. He also established the IPCI, an international Islamic missionary organisation, and wrote several booklets on Islam and Christianity which were widely distributed by the organisation. He was awarded the prestigious King Faisal International Prize in 1986 for his 50 years of missionary work. One focus of his work was providing Muslims with theological tools for defending themselves against active proselytising by Christian missionaries.^{[citation needed]} He used English to get his message across to Muslims and non-Muslims in the western world.

Ahmed Deedat was born in the town of Tadkeshwar, Surat, Bombay Presidency, British India in 1918. His father had emigrated to South Africa shortly after the birth of Ahmed Deedat. At the age of 9, Deedat left India to join his father in what is now known as Kwazulu-Natal. His mother died only a few months after his departure. Arriving in South Africa, Deedat applied himself with diligence to his studies, overcoming the language barrier and excelling in school, even getting promoted until he completed standard 6. However, due to financial circumstances, he had to quit school and start working by the time he was the age of 16.
