50. To the `Ad People (We sent) Hud one of their own brethren. He said: "O my people! worship Allah! ye have no other god but Him. (Your other gods) ye do nothing but invent!

Notes (Tafseer)

1545. Cf. the story of Hud the Messenger of the 'Ad People, in vii. 65-72. There the argument was how other Peoples treated thier prophets as the Makkans were treating Al-Mustafa. Here we see another point emphasized: the insolence of the 'Ad in obstinately adhering to false gods after the true God had been preached to them, Allah's grace to them, and finally Allah's justice in bringing them to book while the righteous were saved. The locality in which the 'Ad flourished is indicated in n. 1040 to vii. 65.
