Lots of Muslims say "our prophet was a very honest man, he was renowned for his honesty in Mecca, Khadija proposed to him because of his honesty" et. al. This is hard to believe. Muhammad was very poor. How many rich women in the world choose a man because of his honesty and not his wealth or his earning capacity? How many Muslim women choose a bridegroom like Khadija did? This act should have been a sunnah long years ago. By the way, how many Muslim women choose a bridegroom? Muslim women are starved of choices and decision making. [[Qur'an, Hadith and Scholars:Women|Women's suppression in Islam]] is a popular reality.
Muslims also try to cite sources like this questions site did.<ref>https://questionsonislam.com/article/prophets-pbuh-marriage-hazrat-khadija</ref> This URL gives two citations for Muhammad's honesty and
you find both of them false on a thorough search.
Why is all this propaganda spread about his honesty? It rules out the chances of raising any doubts about Muhammad's prophethood. Muhammad is honest, although according to poor or false sources. So then, nobody will say he is faking his conversation with Allah.
