Surah Al-Hijr — Ayah 26 (15:26)
وَلَقَدۡ خَلَقۡنَا ٱلۡإِنسَٰنَ مِن صَلۡصَٰلٖ مِّنۡ حَمَإٖ مَّسۡنُونٖ ٢٦
English translation (Saheeh International)
And We did certainly create man out of clay from an altered black mud.
Brief commentary
I created Adam from dried clay, if it is struck it sounds. This clay that he was created from is black and of an altered scent beacuse of the duration it has been left.
