What is ambiguous about the verses I quoted?
That verse does not make up the whole Quran.
Also it is not clear from that verse whether or not it is abrogated as per the commentary in post #7, "It was reported that Ibn `Abbas said that this Ayah was later abrogated by Allah's statement,
(Then when the Sacred Months have passed, kill the idolators wherever you find them)"
From Al-Islam.com (the website referred to in the OP), the following explanation of 4:88 to 4:90 is given at
10. Abrogation in the Qur’an
'What ails you that you are become two parties regarding the hypocrites, when God cast them back [to disbelief] because of what they earned? Seek you to guide him whom God has sent astray? He whom God sends astray, for him you [O Muhiammad] cannot find a road (Qur’an 4:88). They long that you should disbelieve, that you may be upon a level [with them]. So choose not friends from them till they forsake their homes in the way of God: If they turn back [to enmity], then take them and kill them wherever you find them, and choose no friend nor helper from among them (Qur’an 4:89). Except those who seek refuge. . . . (Qur’an 4:90).
Hence, the ordinance in the passage applies to the apostates (
al-murtaddun) who were nonbelievers, [who] then converted to Islam, and then, again, reverted to disbelief. The ruling about them, as stipulated in the passage, is: kill them except in two cases:
1. If they were to seek refuge with a people who [have a covenant with] the Muslims, and to whom they appeal for protection. In such a case, the same ruling applies to them as it applies to the group from whom they have sought protection, in accordance with the terms of the covenant. However, this ruling is conditional on the validity of the covenant. Thus, if the covenant between them and the Muslims is revoked, the ruling would lose its object. We explained, at the beginning of this discussion, that a ruling which is revoked because of the termination of its object has no relation to abrogation whatsoever.
The covenant between the Muslims and the disbelievers was revoked in "Surat al-Tawba" (sura 9). They were given four months to choose between converting to Islam or leaving the Muslim domain. Accordingly, there remained no ground for seeking the kind of protection the verse mentions.'
Have I misunderstood any of the above?
In my opinion
