Allah has sent the Holy Prophet s.a.w as a mercy to the universes. His charecter is a perfect example and guidance for mankind. 

I, and infact most of the muslims have grown up learning about Holy Prophet s.a.w and his excellent and merciful charecter. An old lady used to live close to His house. She used to throw garbase on the Holy Prophet s.a.w whenever he walked past her house. However, He never said anything to her, neither He spoke against her infront of anyone. 

After sometime, the lady got sick and was not able to continue the regular harassment. But, Holy Prophet s.a.w (being concered about the ummah, and each and every person and living things) inquired about her and found out that she was sick. He went to her home to see the old lady out of compassion. 

This gesture of Holy Prophet s.a.w made her come to realization about the Holy Prophet s.a.w and she accepted the islam in the later days.

There are many more such incidents which I will try to cover in other articles on this site.
