“And unto the tribe of Thamúd We sent their brother Ṣáliḥ. ‘O my people,’ said He, ‘Worship God, ye have none other God beside Him.…’ "

"And after Him there appeared from the Riḍván of the Eternal, the Invisible, the holy person of Ṣáliḥ, Who again summoned the people to the river of everlasting life. For over a hundred years He admonished them to hold fast unto the commandments of God and eschew that which is forbidden. His admonitions, however, yielded no fruit, and His pleading proved of no avail. Several times He retired and lived in seclusion. All this, although that eternal Beauty was summoning the people to no other than the city of God. Even as it is revealed: “And unto the tribe of Thamúd We sent their brother Ṣáliḥ. ‘O my people,’ said He, ‘Worship God, ye have none other God beside Him.…’ They made reply: ‘O Ṣáliḥ, our hopes were fixed on thee until now; forbiddest thou us to worship that which our fathers worshipped? Truly we misdoubt that whereunto thou callest us as suspicious.’”⁷All this proved fruitless, until at last there went up a great cry, and all fell into utter perdition."
