Quran 26:155 — The Poets (Al-Shu`ara')

He said, "Here is a camel that will drink only on a day that is assigned to her; a day that is different from your specified days of drinking.

[26:154] "You are no more than a human like us. Produce a miracle, if you are truthful."

[26:156] "Do not touch her with any harm, lest you incur retribution on an awesome day."
