The word(s) "tribes" appears 3 time(s) in 3 verse(s) in Quran in Saheeh International translation.

(1) And We divided them into twelve descendant tribes [as distinct] nations. And We inspired to Moses when his people implored him for water, "Strike with your staff the stone," and there gushed forth from it twelve springs. Every people knew its watering place. And We shaded them with clouds and sent down upon them manna and quails, [saying], "Eat from the good things with which We have provided you." And they wronged Us not, but they were [only] wronging themselves.

(2) Has there not reached them the news of those before them - the people of Noah and [the tribes of] 'Aad and Thamud and the people of Abraham and the companions of Madyan and the towns overturned? Their messengers came to them with clear proofs. And Allah would never have wronged them, but they were wronging themselves.

(3) O mankind, indeed We have created you from male and female and made you peoples and tribes that you may know one another. Indeed, the most noble of you in the sight of Allah is the most righteous of you. Indeed, Allah is Knowing and Acquainted.
