All praise is due to Allah The Exalted, and may Allah raise the rank of our beloved Prophet Muhammad peace be upon him, his kind relatives and companions, and protect his nation from that which he feared for them. Thereafter;
Beware of those who claim matters contrary to the truth of Islam. they claim Prophet Adam was not the first humane, and all human beings originate from him.
Prophet Muhammad descended from Prophet Adam. Prophet Muhammad was not the first creation, as some people claim. Also, beware of those who claim the first creation is the light of our Prophet. This is also invalid. There is no sahih hadith from the Prophet claiming such.
There is, however, a fabricated hadith that the Prophet addressed Jabir by saying: "The first creation is the light of your Prophet, O Jabir."
The hafidh, Ahmad al-Ghumariyy, mentioned this hadith was fabricated in his book entitled, Al-Mughir ^Ala-l-Jami^ is-Saghir and the hafidh, as-Suyutiyy, said this hadith is not confirmed. He mentioned it in two (2) of his books: Al-Fatawa and The Explanation of at-Tirmidhiyy. What was confirmed from the Prophet was that the first creation was the original water, which exists now underneath the ^Arsh.
Adam was the first man and the first human to receive the Revelation of prophethood. He was the first messenger of Allah and he is the ancestor of every member of the humankind. He taught the first people how to live and how to worship Allah correctly. He was an honored and blessed creation of Allah. He was created from soil. In Surat al-Hajj Ayah 5, Allah said:
يَا أَيُّهَا النَّاسُ إن كُنتُمْ فى رَيْبٍ مّـِنَ الْبَعْثِ فَإنَّـا خَلَقْنَاكُم مّـِن تُرَابٍ
سورة الحج - آية 5
which means: [O you people, if you doubt about the matter of the Resurrection, then think about the matter that Adam was created from soil.] That is, should one have difficulty conceptualizing that a person can be resurrected--considering this matter is unlikely, a weak possibility, or one that does not occur--then remember that Allah created Adam from soil. Know that the One Who created Adam from soil has the Power to resurrect you after you turn back into soil.
We humbly ask Allah to enlighten us with the light of Knowledge, and keep us steadfast to the path of truth and righteousness. Ameen.
