Dispelling the Suspicion :
When they say: what is the purpose of this surgery by Gabriel to our Prophet, as Gabriel (Peace be upon him) took out his heart and washed it in a golden basin ….? This is ridiculous reflects their hatefulness towards our Prophet (Allah bless him and grant him peace)…..
If it was about one of the Bible prophets, or one of the Christ Apostles , or a saint; they did not object and did not behave ridiculously.
The question that comes forward is: Is Allah unable to do this?
The answer: No; so there is no doubt about it -By the grace of Allah- this is faith issue, I mean: it does not contradict logic; cause it is specially about the ability of Allah the Almighty and His miracles….
Besides if Allah wanted to show His prophet in a tangible way that He had chosen him, that is removing Satan part from wherever it holds in his noble heart (Allah bless him and grant him peace) taking the heart out of the body and purifying it is an situation Prophet (Allah bless him and grant him peace) saw, and never forgets it, moreover those signs Allah made them as an indications of Prophecy for His prophet; and when the revelation comes to him he was more capable to bear
Like: the elephant event; it happened in the year he was born, it supports the sacredness of his message, and the sacredness of the Holy Land Mecca that he came and made it the direction of worshiping Allah (Qiblah)
So this strange event (splitting chest) is a divine miracle, the tangible piece of Satan is embodied in Prophet (Allah bless him and grant him peace), there is nothing left from Satan part after the satanic piece is removed from his heart and he did see it, this enforces his faith from side, and in another side shows the great capability of Allah Almighty…..
