Al-A'raaf (The Heights)

72. "So We delivered him and those who were with him by a mercy from Us, and We cut away the roots of those who belied Our Signs and were not believers."

The verse implies that Allah brought Hud and those who had believed from among the disbelievers and delivered them from His punishment by His mercy, and He involved those who rejected Allah’s signs and did not believe in His messenger in chastisement so that He cut away the roots of them.

"So We delivered him and those with him by a mercy from Us and We cut away the roots of those belied Our signs and were not believers."

The occurrence of the phrase: "(They) were not believers" in the verse is with the purpose of showing that it was known from their status that they would not have believed if they had remained more.

It is understood from this verse that the people of Hud were caught by the punishment of Allah, and they were destroyed.
