Was only our Prophet ‘Special’

I often hear Muslims say that our beloved Prophet is ‘Special’ – enjoys a rank higher than all the other Prophets. ‘And We have sent you [O Muhammad] not but as a mercy for Al Alamin’ (21:107). Does Prophet Muhammad really enjoy a ‘Special’ status; a rank above the other Prophets?

‘Say [O Muslims]: We believe in Allah and that which has been sent down to us and that which has been sent down to Abraham, Ishmael, Isaac, Jacob and the Tribes, and that which has been given to Moses and Jesus, and that which has been given to the Prophets from their Lord. We make no distinction between any of them, and to Him we have submitted’ (2:136). ‘The Messenger believes in what has been sent down from his Lord, and [so do] the believers. Each one believes in Allah, His Angels, His Books, and His Messengers. [They Say:] We make no distinction between one another of His Messengers’ (2:285).
The Almighty says in the Quran that those who are ‘Muslim’ do not make any distinction between the Prophets.

‘Those Messengers! We preferred some of them to others; to some of them Allah spoke [directly]; others He raised to degrees [of honour]; and to Jesus, the son of Maryam, We gave evidences and supported him with the Holy Spirit’ (2:253). ‘And indeed, We have preferred some of the Prophets above others; and to David We gave the Psalms’ (17:55). ‘And We raised him [Enoch] to a high station’ (19:57). ‘Who can be better in religion than one who submits his whole self to Allah, does good, and follows the way of Abraham – a man of pure faith? And Allah did take Abraham as a Khalil’ (4:125).
God states in the Quran that He is discerning of the Prophets; He endows them with distinct abilities. This is God’s prerogative; in all such exemplifications there is no mention of Prophet Muhammad.

I don’t know if you’ve heard about the ‘Miracle’ that was performed on our beloved Prophet. Gabriel is said to have made an incision in the chest in order to cleanse the Prophet’s heart. Its validity is supposedly based on (94:1) ‘Have We not opened your breast for you [O Muhammad]’. Nashrah literally translates to ‘cut to slice’; implicit that the chest was cut open.
You had alluded to (20:14) in our discussion about As-Salah; (20:25) ‘[Moses] said: O my Lord! Ashrah for me my breast’. I just stumbled onto it whilst glancing through the other verses on the page. This ‘Miracle’ is said to have made Muhammad ‘Masoom’ [Pure and Sinless]; a rank above all the other Prophets. That just can’t be the case if Moses too has experienced the same ‘Miracle’. And further (48:2), ‘That Allah may forgive you [O Muhammad] your sins of the past and the future, and complete His favour on you and guide you on a Straight Path’.
I believe the Almighty inspired courage – broadened the chest, in order that the Prophets may fulfil the arduous task of Prophethood.
