Je was op zoek naar: at what age did you start your own business? (Engels - Swahili)

mind your own business
jali mambo yako mwenyewe

at what time did you arrive
ulifika saa ngapi

did you consider that the sustenance which allah had sent down for you of your own accord you have declared some of it as unlawful and some as lawful?
sema: je! mwaonaje zile riziki alizo kuteremshieni mwenyezi mungu, nanyi mkafanya katika hizo nyengine haramu na nyengine halali.

and that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you;
muwe na nia ya kuishi maisha ya utulivu, kila mmoja ashughulikie mambo yake mwenyewe na afanye kazi kwa mikono yake mwenyewe kama tulivyowaagiza pale awali.

and they say, “our hearts are covered against the affair you call us to, and there is deafness in our ears, and there is a barrier between us and you – therefore mind your own business, we are minding ours.”
na wakasema: nyoyo zetu zimo katika vifuniko kwa hayo unayo tuitia, na masikio yetu yana uziwi, na baina yetu na wewe lipo pazia. basi wewe tenda, nasi tunatenda.
