The Quran

۞ وَإِلىٰ ثَمودَ أَخاهُم صالِحًا ۚ قالَ يا قَومِ اعبُدُوا اللَّهَ ما لَكُم مِن إِلٰهٍ غَيرُهُ ۖ هُوَ أَنشَأَكُم مِنَ الأَرضِ وَاستَعمَرَكُم فيها فَاستَغفِروهُ ثُمَّ توبوا إِلَيهِ ۚ إِنَّ رَبّي قَريبٌ مُجيبٌ

Muhammad Asad

AND UNTO [the tribe of] Thamud [We sent] their brother Salih.¹ He said: "O my people! Worship God [alone]: you have no deity other than Him. He brought you into being out of the earth,² and made you thrive thereon.³ Ask Him, therefore, to forgive you your sins, and then turn towards Him in repentance - for, verily, my Sustainer is ever-near, responding [to the call of whoever calls unto Him]!"⁴

A short account of the tribe of Thamud (the "Second 'Ad" of pre-Islamic poetry) is found in surah 7, note 56. Salih is believed to have been the second prophet, after Hud, sent to the Arabs.
I.e., out of organic substances which derive their nourishment - and hence their capability of development, proliferation and evolution - either directly or indirectly from the earth (Razi). This is evidently also the meaning of the Qur'anic references to man as "created out of dust" (cf. 3:59, 18:37, 22:5 and 30:20).
See 7:74 and the corresponding notes.
See 2:186.
