Born in Dar-es-salaam in Tanzania to British parents , his father (born in England), Gavin Green, was a colonial administrator in the then extant British Empire. At an early age he moved back to the UK with his parents. His mother is of original Polish origin  .
At the age of ten he attended a Roman Catholic Monastic boarding school at Gilling Castle and then went onto Ampleforth College and went on to study history in the University of London. However, he left his education unfinished in an effort to devote himself to Islamic works.
Green worked for five years in the London Central Mosque and Islamic Cultural Centre as the Visits and English Dawa Co-ordinator, but now runs a consultancy, Green and Chambers Consulting, with his friend and fellow convert to Islam Yusuf Chambers, as well as making regular appearances on PeaceTV and Islam Channel.
 Personal life
Green had two wives, now one, who is British-born Muslim of Pakistani origin and has eleven children. Whilst claiming two wives, Green was asked in an interview: Does not the British law prohibit bigamy? Green responded "It does. Yet several Britishers are bigamists. But those who practise bigamy can protect the second marriage under the provisions of 'common law wives'. Under this children out of such marriages are legitimate and wives inherit property."
