Creation of First Man/ prophet Adam(as) and his Descendants

Al-Salsaal min al-teen (clay made from mud) is that which has not been made into pottery. Any mud or clay that dries is described as salla saleelan (rattling or clattering) … i.e., it makes a noise like new pottery. Thus salsaal is likened to pottery, as in the verse,  

“He created man (Adam) from sounding clay like the clay of pottery”

[al-Rahmaan 55:14 – interpretation of the meaning]

All of this is confirmed by the hadeeth of Abu Moosa al-Ash’ari who said: “I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: ‘Allah created Adam from a handful that He gathered from the entire earth, so the sons of Adam come like the earth. Some of them are red, some are white, some are black and some are in between. Some of them are easy, some of them are difficult, some are evil and some are good.”

(Narrated by al-Tirmidhi, 2955; Abu Dawood, 4693. Al-Tirmidhi said that this hadeeth is hasan saheeh, and it was classed as saheeh by Ibn Hibbaan, 14/29; al-Haakim, 2/288; and al-Albaani in Saheeh Abi Dawood, 3926). 

This is how Adam was created: from the earth – i.e. from its dust – which was then mixed with water to form mud, which then became black, stinking mud. And this dust was created from the earth which is partly sand and when it is mixed it becomes sounding clay like the clay of pottery.
