All praises belong to Allah and may the peace and blessings of Allaah be upon our noble Prophet Muhammad صَلَّى الله عليه وسلم.
As a good believing Muslim with sound creed and Islamic knowledge, it is not befitting to be spreading this kind of reports amongst the Muslims not to talk of the non Muslims.
Don’t be deceived by the ranking and compilations made by one Michael Hart by making our Noble Prophet Muhammad صَلَّى الله عليه وسلم Number 1 on the list.
Allah has indeed made him the best of mankind and that is enough for us to accept and no doubt about it.
In a situation whereby a Kaafir is made number 2 and other Prophets of Allah are below kufaar of different types is totally unacceptable in all manners.
Muslims should therefore reject compilations like this as it contravenes our belief and methodology.
We do not distinguish between the Prophets of Allah not to talk of making kufaar above them in ranking.
Anyone who believes in ranking like this may be treading the path of Kufr if care is not taken.
We pray Allah سبحانه وتعالى guides our hearts to what is right and bestow on us the ability to follow it.

Jazaak Allaahu khayran! I also agree with these. We ask Allah to pardon us all for all the sins we committed either intentionally or otherwise.

The so called compilation does not even state Muhammad is influencial positively or negatively, I wonder why majority apologists Muslims use this strawman argument whenever they are out of juice.

Michael Hart gave his reasons, and it was, Muhammad was both the political key leader that established Islam and it development(proselytizing, conquest) and also the key moral standard for Muslims that wrote the Quran which is closely base on his ideas, Jesus on the other hand was only the key moral standard of Christianity while St. Paul was the founder of Christianity development. So he feel like placing Muhammad as number one.
