I collected some information about Adam and Muhammad

Adam was the first man created by God according to Jewish, Christian and Islamic traditions. He is considered a prophet by the Jewish, Islamic, Mormon, Mandaean and Bahá'í faiths. He is also commemorated as a patriarch in the Calendar of Saints of the Lutheran Church - Missouri Synod with Eve on December 19.

Muhammad ibn ‘Abd Allāh ( ; also Mohammed, Muhammed, Mahomet, and other variants) (c. 570 Mecca - June 8th 632 CE Madina) was the founder of Islam and is regarded by Muslims as the last messenger and prophet of God (Arabic: Allah). Muslims do not believe that he was the creator of a new religion, but the restorer of the original, uncorrupted monotheistic faith of Adam, Abraham and others. They see him as the last and the greatest in a series of prophets.

Thanks a lot, sister
