“وَإِذْ تَقُولُ لِلَّذِي أَنْعَمَ اللَّهُ عَلَيْهِ وَأَنْعَمْتَ عَلَيْهِ أَمْسِكْ عَلَيْكَ زَوْجَكَ وَاتَّقِ اللَّهَ وَتُخْفِي فِي نَفْسِكَ مَا اللَّهُ مُبْدِيهِ وَتَخْشَى النَّاسَ وَاللَّهُ أَحَقُّ أَنْ تَخْشَاهُ فَلَمَّا قَضَى زَيْدٌ مِنْهَا وَطَرًا زَوَّجْنَاكَهَا لِكَيْ لاَ يَكُونَ عَلَى الْمُؤْمِنِينَ حَرَجٌ فِي أَزْوَاجِ أَدْعِيَائِهِمْ إِذَا قَضَوْا مِنْهُنَّ وَطَرًا وَكَانَ أَمْرُ اللَّهُ مَفْعُولاً”- الأحزاب 37

And (remember) when you said to him (Zaid bin Hârithah (may Allah be pleased with him) - the freed-slave of the Prophet (peace be upon him)) on whom Allâh has bestowed Grace (by guiding him to Islâm) and you (O Muhammad (peace be upon him) too) have done favor (by manumitting him): "Keep your wife to yourself, and fear Allâh." But you did hide in yourself (i.e. what Allâh has already made known to you that He will give her to you in marriage) that which Allâh will make manifest, you did fear the people (i.e., their saying that Muhammad (peace be upon him) married the divorced wife of his manumitted slave) whereas Allâh had a better right that you should fear Him. So when Zaid had accomplished his desire from her (i.e. divorced her), We gave her to you in marriage, so that (in future) there may be no difficulty to the believers in respect of (the marriage of) the wives of their adopted sons when the latter have no desire to keep them (i.e. they have divorced them). And Allâh's Command must be fulfilled.
(Surat Al-Ahzab- verse No. 37)

It seems that the majority of Muslims refuses this fact and interprets it according to their own whims. This what the preacher said. Now we present to the respected reader our comment on what he said:
Firstly, Mohammed PBUH did not confess of anything in the Holy Koran. These were the words of Allah not the words of the messenger. Secondly, I wonder what are these wrongdoings which the preacher attributed in particular to the Messenger of Allah? In fact, there is no such thing at all for the messenger committed adultery nor did he shed blood of a soul, nor did he lie to anyone, nor envy him, nor did he stir a conspiracy for anyone of mankind, nor was he lenient in reporting the message he was delegated to perform, nor did he diverge away from it, nor did he accept idolatry of disbelievers, nor did he drink alcohol, nor did he steal, nor did he oppress people nor did he frighten them nor was he unjust with their rights nor did he do anything of what scribers of gospel had attributed to any prophet or more as know everyone who read this book. Otherwise, would this Christian preacher lead us to any source saying that the messenger had committed any of these things! Actually, there is nothing of this not in Koran nor in the prophetic traditions, or in the books of biography and history denoting this.
