According to the Bukhari Hadith vol.2 page 7, in the glossary Jizya is a "Head-tax imposed by Islam on the people of the Scriptures and other people who have a releaved book (Non-Muslims) when they are under Muslim rule." Muslims even say that Christians and Jews should be grateful for the Jizya, because without it, they would have no right to dwell in Muslim lands without being killed.
Kwa mujibu wa Bukhari Hadith juzuu ya 2 uk.7, kwenye farahasa, Jizya ni "Kodi ya kichwa iliyowekwa na Waislam kwa watu wa Maandiko na watu wengine wenye kitabu kilichofunuliwa (wasio Waislam) wakati walipokuwa chini ya utawala wa kiislam." Waislam hata wanasema kuwa Wakristo na Waislam na Wayahudi wanapaswa kushukuru kuwepo kwa Jizya, kwa sababu bila hiyo, hawangekuwa na haki ya kuishi kwenye nchi za kiislam bila kuuawa.
