And We have already sent messengers before you to their peoples, and (30:47)

Almuntakhab Fi Tafsir Alquran Alkarim

And before you. O Muhammad We sent Messengers conveying Our divine message to their people. They presented them with clear and plain revelations guiding out of darkness and superstitions of later times and out of want of spiritual and intellectual sight into illumination and enlightenment -but they counselled deaf and closed their hearts ears-. And by consequence We avenged our right by inflicting retributive punishment upon those who were steeped in crime. At the same time it was incumbent on Us to save and deliver to safety those whose hearts reflected the image of religious and spiritual virtues

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

(30:47) We sent Messengers before you to their respective nations, and they brought Clear Signs *71 to them. Then We took vengeance upon those who acted wickedly. *72 It was incumbent on Us to come to the aid of the believers.

And We have already sent messengers before you to their peoples, and meaning

*71) That is, "One kind of the Signs are those which are scattered in the world around man, which he comes across at every moment of his life, one of which is the system of the circulation of winds, as mentioned in the preceding verse. The other kind of the Signs are those which the Prophets of Allah brought in the form of the miracles and Divine Revelations and the extraordinary pure characters and their healthy and life-giving influence on human society. Both kinds of the Signs point to the same Reality, which is this: The Tauhid which the prophets teach is based on the Truth. Each of these Signs supports the other. The Signs of the universe testify to the truth of what the Prophets say, and the Signs brought by the Prophets explain the reality being pointed out by the Signs of the universe.
*72) "The guilty ones": those who remained blind to these two kinds of the Sighs and persisted in their denial of Tauhid and their rebellion against God.
