Surah 91. Ash-Shams, Ayah 12

The prophet Salih was given a certain she-camel as a Sign, a test case, "This she-camel of Allah is Sign unto you: so leave her to graze in Allah's earth and let her come to no harm, or ye shall be seized with a grievous punishment" (vii. 73). But they plotted to kill her and sent the most wicked man among them to dare and do that deed of impiety. It was probably when she came to drink at the stream that she was hamstrung and killed. See xxvi. 155, and liv. 27.
