And We made his descendants those remaining [on the earth] (37:77)

Almuntakhab Fi Tafsir Alquran Alkarim

And We destined his posterity to be the survivors who inhabit the earth

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(37:77) and made his offspring the only ones to survive, *42

And We made his descendants those remaining [on the earth] meaning

*42) This can have two meanings: (1) That the progeny of the people who were opposing the Prophet Noah was made extinct and the Prophet Noah's progeny alone was allowed to survive; and (2) that the whole human race was made extinct, and only the Prophet Noah's progeny was allowed to inhabit the earth after that. The commentators generally have adopted this second meaning, but the words of the Qur'an are not explicit in this regard and no one knows the reality except Allah.
