(V.47:1) It is obligatory to have Belief in the Messengership of the Prophet Muhammad صلى الله عليه وسلم.
Narrated Abu Hurairah رضي الله عنه: Allâh’s Messenger صلى الله عليه وسلم said, "By Him (Allâh) in Whose Hand Muhammad’s soul is, there is none from amongst the Jews and the Christians (of these present nations) who hears about me and then dies without believing in the Message with which I have been sent (i.e. Islâmic Monotheism), but he will be from the dwellers of the (Hell) Fire." (Sahih Muslim , the Book of Faith, Vol.1, Chapter No.240). See also (V.3:85) and (V.3:116).
(V.47:4) See the footnote of (V.2:190) and (V.9:20).
(V.47:6) Narrated Abû Sa‘îd Al-Khudrî رضي الله عنه: Allâh’s Messenger صلى الله عليه وسلم said, "The believers, after being saved from the (Hell) Fire, will be stopped at a bridge between Paradise and Hell and mutual retaliation will take place among them regarding the wrongs they have committed in the world against one another. After they are cleansed and purified (through the retaliation), they will be admitted into Paradise; and by Him in Whose Hand Muhammad’s soul is, everyone of them will know his dwelling in Paradise better than he knew his dwelling in this world." (Sahih Al-Bukhari, Vol.8, Hadith No.542)
