All the true prophets of God would never contradict themselves, they are bound to tell the truth as they speak on behalf of the Creator of the universe. If you examine the lives of all the prophets it’s obvious that they stand for virtue and integrity, while none of them were perfect they never taught anything sinful.
Regarding Muhammad, Islam’s so-called prophet we see that he taught sinful practices. Some of them are fornication, covetousness, hatred and lying. In this article, we’ll view two contradictory sayings of Muhammad.
Please note that both Hadith’s are graded as Sahih, therefore, they are both authentic and accepted. In Sahih Muslim 2607c Abdullah reports that Muhammad said “It is obligatory for you to tell the truth” this means you don’t have a choice it’s an obligation.
The root word for Obligatory would be Obligation, the definition according to Websters-Dictionary is “the action of obligating oneself to a course of action (as by a promise or vow)”[1]

Muhammad says Muslims are bound to their vow, they are not to tell any lies as remaining truthful leads to paradise. If one should choose to lie they would lead them to obscenity[2] which then leads to hell-fire. This person is counted as a liar in the eyes of Allah. The above hadith might seem somewhat noble the problem is that Muhammad contradicts himself in the following hadith.

This hadith from Jami at-Tirmidhi says that what Muhammad taught was halal (permissible) to lie to your wife, during war and to other people in order to bring peace. This cannot be the teachings of a prophet of God. If this is the case then Muhammad according to his own words in Sahih Muslim 2607c is in hell-fire. It’s not hard to see that he contradicts himself constantly and teaches sinful practices.
According to the Bible, Muhammad is in hell, in the book of Revelation God says all liars will have their part in the lake of fire.[3]
Conclusion
Our duty is to speak the truth, we love Muslims and want them to know the truth of what Islam teaches. We want them to have salvation by coming to Jesus Christ for eternal life by trusting in His death, burial and Resurrection. Only the Son of God can wash you clean of your sins, Muhammad cannot do anything for you. He was a sinful man and a liar, but Jesus Christ never lied and said if you believe in Him you will have everlasting life because He is the Resurrection and the Life[4] trust in Christ if you want to be saved.
