Cat steven, now Yusuf Islam (born Steven Demetre Georgiou; 21 July 1948 in Marylebone, London, England) originally and commonly known by his former stage name Cat Stevens, is an English musician. He is a singer-songwriter, multi-instrumentalist, educator, philanthropist, and prominent convert to Islam.
While on holiday in Marrakech, Morocco, shortly after visiting Ibiza, Stevens was intrigued by the sound of the Aḏhān, the Islamic ritual call to prayer, which was explained to him as "music for God". Stevens said, "I thought, music for God? I’d never heard that before – I’d heard of music for money, music for fame, music for personal power, but music for God!"

thogh, he abandoned music but see what he has to say about it.......

Following his conversion, Yusuf abandoned his music career. When he became a Muslim in 1977, he said, the Imam at the mosque was told that he was a pop star, and he told Yusuf that "it was fine to continue as a musician", so long as the songs were "morally acceptable". But Yusuf says he knew there were aspects of the music business, such as "vanity and temptations", that did go against the teachings of the Qur'an, and this was the primary reason he gave for retreating from the spotlight.

Yusuf gradually resumed his musical career in the 1990s. His initial recordings had not included any musical instruments other than percussion, and featured lyrics about Islamic themes. He invested in building his own recording studio which he named Mountain of Light Studios in the late 1990s, and he was featured as a guest singer on "God Is the Light", a song on an album of nasheeds by the group Raihan. In addition, he invited and collaborated with other Muslim singers, including Canadian artist Dawud Wharnsby. After Yusuf's friend, Irfan Ljubijankic, the Foreign Minister of Bosnia and Herzegovina, was killed by a Serbian rocket attack, Yusuf appeared at a 1997 benefit concert in Sarajevo and recorded a benefit album named after a song written by Ljubijankic, I Have No Cannons That Roar
