So reporting on Islamic terrorists makes you hateful? If you had read any of Mr Spencer’s books you would realize he generally relies on the Islamic hadiths for whatever he says about Muhammad. Hadiths Muslims in Islamic countries generally accept. His style sometimes might be a bit crude, but you cannot accuse him of being hateful simply because he reads the islamic sources and happens to find in them the interpretation of the terrorists as well as Orthodox Islamic authorities.
But this event is actually mentioned in the quran
SHAKIR: And when you said to him to whom Allah had shown favor and to whom you had shown a favor: Keep your wife to yourself and be careful of (your duty to) Allah; and you concealed in your soul what Allah would bring to light, and you feared men, and Allah had a greater right that you should fear Him. But when Zaid had accomplished his want of her, We gave her to you as a wife, so that there should be no difficulty for the believers in respect of the wives of their adopted sons, when they have accomplished their want of them; and Allah’s command shall be performed. 33:37
and in case it be accused I have made this up
And when (idh is dependent because of [an implied preceding] udhkur, ‘mention [when]’) you said to him to whom God had shown favour, by [guiding him to] Islam, and to whom you [too] had shown favour: by manumitting him — this was Zayd b. Hāritha, who had been a prisoner of war before [the coming of] Islam (in the period of al-jāhiliyya). The Messenger of God (s) purchased him before his call to prophethood, and then manumitted him and adopted him as his son — ‘Retain your wife for yourself and fear God’, before divorcing her. But you had hidden in your heart what God was to disclose, [what] He was to manifest of your love for her and of [the fact] that should Zayd part with her you would marry her, and you feared people, would say, ‘He has married his son’s wife!’, though God is worthier that you should fear Him, in all things, so take her in marriage and do not be concerned with what people say. Zayd subsequently divorced her and her [obligatory] waiting period was completed. God, exalted be He, says: So when Zayd had fulfilled whatever need he had of her, We joined her in marriage to you — the Prophet consummated his marriage with her without [the customary] permission [from her legal guardian] and gratified the Muslims with [a feast of] bread and meat — so that there may not be any restriction for the believers in respect of the wives of their adopted sons, when the latter have fulfilled whatever wish they have of them. And God’s commandment, that which He has decreed, is bound to be realized. Tafsir Al Jalalayn
Bahais and Muslims are so quick to deny anything bad said about Muhammad and that is the only criteria. If it is negative, you cannot trust it. If it embarrasses the prophet, well it obviously cannot be trusted. This is another aspect which makes little sense in Islam, how is it that only the sources you use and interpret are the correct sources but any sources Christians use well they can’t possibly be true?
