The conduct of the Prophet (PBUH) with new Muslims

The Prophet of Allah, sallallaahu ‘alayhi wa sallam, was extremely eager for people to be guided to Islam, to the point that Allah Said to him (what means): «Perhaps, [O Muhammad], you would kill yourself with grief that they will not be believers.» Allah The Almighty Also Said (what means): «Then perhaps you would kill yourself through grief over them, [O Muhammad], if they do not believe in this message, [and] out of sorrow.» 
At-Tabari (a scholar) said: “Allah meant by that; Perhaps, O Muhammad you would kill and destroy yourself over the people who told you: ‘We will not believe you until you bring forth a spring from the ground’, out of their defiance against their Lord.”You would destroy yourself” because they do not believe in the Book that was revealed to you or believe that it is from Allah, out of eagerness and sadness from their turning away and rejecting belief in you.” Allah has described him as being eager for the guidance of all people,when He said (what means): «Verily, there has come unto you a Messenger from amongst yourselves [i.e. whom you know well]. It grieves him that you should receive any injury or difficulty. He is anxious over you, for the believers full of pity, kind, and merciful.» As-Si’di (ascholar) said: “The words: “It grieves him that you should receive any injury or difficulty” mean that anything that is difficult upon you is difficult upon him. The words: “He is anxious over you” mean that he, sallallaahu ‘alayhi wa sallam, loves all goodness for you, and strives his hardest  The Prophet of Allah, sallallaahu ‘alayhi wa sallam, was extremely eager for people to be guided to Islam, to the point that Allah Said to him (what means): «Perhaps, [O Muhammad], you would kill yourself with grief that they will not be believers.»  Allah The Almighty Also Said (what means): «Then perhaps you would kill yourself through grief over them, [O Muhammad], if theydonot believe in this message, [and] out of sorrow.»
