Al-Isra 17:59

<h2>The Reason why Allah did not send Signs or Miracles</h2><p>Sa`id bin Jubayr said, "The idolators said: `O Muhammad, you claim that before you there were Prophets, among whom was one to whom the wind was subjugated, and another who could bring the dead back to life. If you want us to believe in you, ask your Lord to turn As-Safa' into gold for us.' Allah conveyed to him by inspiration (Wahy): `I have heard what they have said. If you wish, I will do what they say, but if they do not believe after that, the punishment will come down upon them, because after the sign has been sent, there is no room for speculation. Or if you wish, I will be patient with your people and give them more time.' He said:</p><p>«يَارَبِّ اسْتَأْنِ بِهِم»</p><p>(O Lord, give them more time.)"

Naught hindereth Us from sending portents save that the folk of old denied them. And We gave Thamud the she-camel - a clear portent save to warn.

And We refrain from sending the signs, only because the men of former generations treated them as false: We sent the she-camel to the Thamud to open their eyes, but they treated her wrongfully: We only send the Signs by way of terror (and warning from evil).

And nothing stops Us from sending the Ayat (proofs, evidences, signs) but that the people of old denied them. And We sent the she-camel to Thamud as a clear sign, but they did her wrong. And We sent not the signs except to warn, and to make them afraid (of destruction).

Nothing prevents Us from sending miraculous signs, except that the ancients called them lies. We gave Thamood the she-camel, a visible sign, but they mistreated her. We do not send the signs except to instill reverence.
