What can we learn about Prophet Muhammad (saw) from the hadith `Abdur-Rahman bin Abu Bakr narrated?
 Narrated `Abdur-Rahman bin Abu Bakr:                     We were one hundred and thirty men sitting with the Prophet. The Prophet said, "Have anyone of you any food with him?" It happened that one man had one Sa of wheat flour (or so) which was turned into dough then. After a while a tall lanky pagan came, driving some sheep. The Prophet asked, 'Will you sell us (a sheep), or give (it to) us as a gift?" The pagan said, "No, but I will sell it " So the Prophet bought from him a sheep which was slaughtered, and then the Prophet ordered that the liver, the kidneys, lungs and heart, etc., of that sheep be roasted. By Allah, none of those one hundred and thirty men but had his share of those things. The Prophet gave to those who were present, and also kept a share for those who were absent He then served that cooked sheep in two big trays and we all ate together our fill; yet there remained a part of it in those two trays which I carried on the camel.
