Quran 25:20 — The Statute Book (Al-Furqan)

We did not send any messengers before you who did not eat food and walk in the markets. We thus test you by each other; will you steadfastly persevere? Your Lord is Seer.

[25:19] They have disbelieved in the message you have given them, and, consequently, you can neither protect them from the retribution they have incurred, nor can you help them in any way. Anyone among you who commits evil, we will commit him to severe retribution.

[25:21] Those who do not expect to meet us said, "If only the angels could come down to us, or we could see our Lord (we would then believe)!" Indeed, they have committed a gross arrogance, and have produced a gross blasphemy.
