Some questions for those who like to learn through questions:
1) Quote a verse where Allaah clearly negates the idea of the Prophet (sallallaahu alayhe wa sallam) guiding someone. Then explain which of the three types of guidance is being negated.
2) Quote a verse where Allaah clearly affirms the idea of the Prophet (sallallaahu alayhe wa sallam) guiding someone. Then explain which of the three types of guidance is being affirmed.
3) Explain how the two verses are understood together harmoniously, clarifying the issue for people who would claim that there is a contradiction between the two verses.
4) What could that fourth type of hidaayah mentioned in that old post on ST.net (link quoted above) possibly be? (with mention of the text that estbalishes the fourth seperate meaning of hidaayah)
