AL-INSAN الانسان
“Man.” The title of the LXXVIth Surah of the Qur’an, called also Suratu ‘d-Dahr, both words occurring in the first verse: “Did there not pass over man (insan) a long space of time (dahr) during which he was a thing not worthy of remembrance.”
Some take these words to be spoken of Adam, whose body, according to tradition, was first a figure of clay, and was left for forty years to dry, before God breathed into it; but others understand them of man in general and of the time he lies in the womb. (See al-Baizawi, in loco.)
