the messenger of allah, may allah exalt his mention, was the most humble person. he was so humble that if a stranger were to enter the masjid and approach the prophet's sitting place and he was sitting with his companions one would not be able to distinguish him from his companions.

anas bin malik, with whom allah is pleased, said:

'once, while we were sitting with the messenger of allah , may allah exalt his mention, in the masjid, a man on his camel came in, after he tied it with a rope, he asked: 'who of you is muhammad?' the messenger of allah, may allah exalt his mention, was sitting on the ground while he was leaning, with his companions. we directed the bedouin, saying: 'this white man, who is leaning on the ground.' the prophet, may allah exalt his mention, did not differ nor distinguish himself from his companions.

the prophet, may allah exalt his mention, would not hesitate to help the poor, needy and widows in their needs. anas b. malik, with whom allah is pleased, said:

'a woman from the people of madinah who was partially insane said to the prophet, may allah exalt his mention, : 'i have to ask you about something.' he helped her and took care of her needs.'  (bukhari #670)
