Yes, up to four, with a firm condition of justice among them. The Quran says that whoever fears he will not be just should marry one (4:3), and notes that perfect fairness in feeling is not possible (4:129), so the duty is justice in spending, time and treatment. Local law and agreements may add conditions.
Na ikiwa mnaogopa kuwa hamtowafanyia mayatima uadilifu, basi oeni mnao wapenda katika wanawake, wawili au watatu au wane. na mkiogopa kuwa hamwezi kufanya uadilifu, basi mmoja tu, au wale ambao mikono yenu ya kulia imewamiliki. Kufanya hivi ndiko kutapelekea msikithirishe wana.
Wala hamtaweza kufanya uadilifu baina ya wake, hata mkikakamia. Kwa hivyo msimili moja kwa moja mkamwacha (mmojapo) kama aliye tundikwa. Na mkisikizana na mkamchamngu basi Mwenyezi Mungu ni Mwingi wa maghfira na Mwenye kurehemu.
