the answer:

the most important point to understand is that he was the beloved prophet of allah subhanahu ta’aalah. allah commanded his chest to be split open and heart washed.

there should not be any problem in accepting that as it is confirmed.

and since he was a prophet he was better than us in every manner, hence a role model. he was a human being because allah mentions in the holy quran at various places about prophet muhammad being created as a human being. that is what makes him a prophet of allah and allah bestowed upon him some blessings.

more to this subject:

allaah, may he be glorified and exalted, honored his prophets and messengers with immense blessings, first and foremost among which, and the highest in status, was the blessing of prophethood, as he chose them to be close to him and to bestow his mercy upon them. 

allaah says (interpretation of the meaning): 

“but allaah chooses of his messengers whom he wills”

[aal ‘imraan 3:179] 

“and also some of their fathers and their progeny and their brethren, we chose them, and we guided them to the straight path”

[al-an’aam 6:87] 

allaah, may he be glorified and exalted, chose his prophet and close friend muhammad (peace and blessings of allaah be upon him) for more honor and bestowed a high status upon him, as allaah says (interpretation of the meaning):  

“had not the grace of allaah and his mercy been upon you (o muhammad صلى الله عليه وسلم), a party of them would certainly have made a decision to mislead you, but (in fact) they mislead none except their own selves, and no harm can they do to you in the least. allaah has sent down to you the book (the qur’aan), and al­hikmah (islamic laws, knowledge of legal and illegal things, i.e. the prophet’s sunnah — legal ways), and taught you that which you knew not. and ever great is the grace of allaah unto you (o muhammad صلى الله عليه وسلم)”

[an-nisa’ 4:113] 

as part of this grace, allaah opened the chest of his noble messenger muhammad (peace and blessings of allaah be upon him) and he referred to this great blessing in a sorah of the qur’an that will be recited until the day of resurrection. it is called sorat ash-sharh. 

allaah says (interpretation of the meaning): 

“have we not opened your breast for you ((o muhammad?”

[ash-sharh 94:1] 

the opening of the chest of the prophet (peace and blessings of allaah be upon him) points to a number of important meanings: 

1 – allaah opened his heart to islam as a religion and law, which is the greatest thing to which the heart may be opened. this is the interpretation of ibn ‘abbaas, as reported by al-bukhaari in a mu’allaq report in his saheeh (kitaab al-tafseer/baab soorat al-sharh, p. 982). 

2 – allaah opened the chest of his prophet muhammad (peace and blessings of allaah be upon him) in order to fill it (his heart) with wisdom, knowledge and faith, as it was interpreted by al-hasan al-basri. the scholars mentioned in their commentaries on this incident of the opening of the prophet’s chest, which happened twice during his life. 

the first occurred when he was small and living among banu sa’d. 

it was narrated from anas ibn maalik (may allaah be pleased with him) that jibreel came to the messenger of allaah (peace and blessings of allaah be upon him) when he was playing with the other boys. he took hold of him and threw him to the ground, then he opened his chest and took out his heart, from which he took a clot of blood and said: “this was the shaytaan’s share of you.” then he washed it in a vessel of gold that was filled with zamzam. then he put it back together and returned it to its place. the boys went running to his mother – meaning his nurse – and said: muhammad has been killed! they went to him and his colour had changed. anas said: i used to see the mark of that stitching on his chest.

narrated by muslim (162). 

the second occurred on the night of the isra’. 

abu dharr used to narrate that the messenger of allaah (peace and blessings of allaah be upon him) said: “the roof of my house was opened when i was in makkah, and jibreel (peace and blessings of allaah be upon him) came down and split open my chest, then he washed it with zamzam water. then he brought a golden basin filled with wisdom and faith and emptied it into my chest. then he sealed it…” narrated by al-bukhaari (349) and muslim (163). 

al-haafiz ibn hajar (may allaah have mercy on him) said in fath al-baari (7/204): 

some of them denied that his chest was opened on the night of the isra’, and said that this only happened when he was small and living among banu sa’d. but that cannot be denied because there are many reports about it. … all that has been narrated about his chest being opened, his heart being taken out and other extraordinary events must be accepted without objection or trying to interpret it other than what it appears to mean, because allaah is able to do all that and none of that is impossible. al-qurtubi said in al-mufhim: no attention should be paid to denials of the opening of his chest on the night of the isra’, because the narrators are trustworthy and well known. end quote. 

the incident of his chest being opened is also mentioned in some reports at other times, at the age of ten, and when his mission began, but these are weak reports. see: al-seerah al-nabawiyyah al-saheehah (1/103). 

ibn katheer said in tafseer al-qur’aan il-‘azeem (4/677): 

allaah says “have we not opened your breast for you (o muhammad)?” meaning, did we not open your heart for you, i.e., we illuminated it etc. this is like the verse in which allaah says (interpretation of the meaning): “and whomsoever allaah wills to guide, he opens his heart to islam.” [al-an’aam 6:125]. 

and it was said that what is meant by the verse “have we not opened your breast for you (o muhammad)?”  is the opening of his chest on the night of the isra’, but there is no contradiction because the opening of his chest includes what was done on the night of the isra’ as well as the metaphorical meaning of opening his heart. and allaah knows best. end quote. 

3 – it says in rooh al-ma’aani (30/166): 

it was said that what is meant is: did we not relieve your distress and worry by showing you the reality of things and the insignificance of this world, so that enabled you to bear hardship by mans of turning to allaah with du’aa’.  

it was narrated from the majority that what is meant is:  did we not bestow upon him wisdom and enable him to receive that which was revealed to him after it was difficult for him? 

4 – ibn ‘ashoor said in al-tahreer wa’l-tanweer (1/4850): 

opening his breast is a metaphor for the blessings that were bestowed upon him and enabling him to attain all levels of perfection, and informing him that allaah is pleased with him, and glad tidings of the victory that the religion would attain. end quote. 

see: subul al-huda wa’l-rashaad (2/59). 

5 – shaykh ibn ‘uthaymeen (may allaah have mercy on him) said in tafseer soorat al-sharh (p.1): 

this opening is metaphorical, not physical. the opening of the heart may be done so that it is able to receive the decree of allaah of both types, the shar’i decrees of allaah, which means religion, and the decree of allaah which has to do with the calamities that may befall man. end quote.  

and allaah knows best.
