 The name means "gift of the most merciful", "ar-Rahman" being one of the names of God in the Qur'an, which give rise to the Muslim theophoric names.The letter "a" of the "al-" is unstressed, and can be transliterated by almost any vowel, usually by "u".Because the letter "r" is a sun letter, the letter "l" of the "al-" is assimilated to it.
