Mu myaka ya kera, Islam yari iri mu bihe byo kwagura ubwami bwayo, ndetse n’idini yayo. Islam yatangiye kwagura ubwami bwayo mu mwaka wa 632, nyuma y’urupfu rw’Intumwa Muhamadi.
Mu gihe Uburayi bwari bugowe, buri mu bihe by’umwijima, Uburasirazuba bwo hagati bwari mu gihe cyo gutera imbere mu bukungu no gutera imbere mu bumenyi.
Ubwami bwa Islam bwatangiye muri 610, kugeza igihe ubwami bwa Ottoman bwaviriyeho mu 1924.
