This is from Aisha Bewley’s translation of Bukhari, Chapter 9: Clothing in the Prayer:
XI: What is said about the thigh
It is related from Ibn ‘Abbas, Jarhad and Muhammad ibn Jahsh from the Prophet, may Allah bless him and grant him peace, “The thigh is one of the private parts.”
Anas said, “The Prophet, may Allah bless him and grant him peace, uncovered his thigh.”
The hadith of Anas is stronger, but the hadith of Jarhad is more complete in order to resolve the disagreement of the scholars.
Abu Musa said, “The Prophet, may Allah bless him and grant him peace, covered his knees when ‘Uthman entered.”
Zayd ibn Thabit said, “Allah sent down revelation on His Messenger, may Allah bless him and grant him peace, while his thigh was resting on my thigh and it became so heavy that I was afraid that it would bruise my thigh.”
It is related from Anas, “The Messenger of Allah, may Allah bless him and grant him peace, raided Khaybar and we prayed the Morning Prayer there when it was still dark. The Prophet of Allah, may Allah bless him and grant him peace, mounted, Abu Talha mounted, and I followed behind Abu Talha. The Prophet, may Allah bless him and grant him peace, rode quickly through the lane of Khaybar and my knee touched the thigh of the Prophet of Allah, may Allah bless him and grant him peace. He had removed the wrapper from his thigh so that I could see the whiteness of the thigh of the Prophet of Allah, may Allah bless him and grant him peace. When he entered the town, he said, ‘Allah is greater! Khaybar is ruined. When we alight in the courtyard of a people, it is an evil morning for those who have been warned.’ He said this three times. The people came out for their jobs and said, ‘Muhammad!'”
XI: What is said about the thigh
As you can see, “thigh” is a euphemism for the private parts of Muhammad.
Obviously, this is not the behaviour of a good and true prophet. Thus you know Muhammad was a false prophet, for a false god, Allah, for a false religion, Islam, without even a false book, Koran.
But, Infidel, you can’t be sure that “thigh” means the private parts! Perhaps this hadith from Muhammad?
Muhammad b. Jahsh told that God’s Messenger came upon Ma’mar when his thighs were uncovered and said, “Cover your thighs, Ma’mar, for the thighs are private parts.”
Mishkat al-Masabih 3114
But, Infidel, it has to be explicitly Sahih for me to believe it! Perhaps this hadith then?
The Messenger of Allah sat with us and my thigh was uncovered. He said: “Do you not know that thigh is a private part?”
Sunan Abi Dawud 4014
The head of the Messenger of Allah would rest in the lap of one of us when she was menstruating, and he would recite Qur’an.
