Offering Food and Showing Courtesy

“During one of his expeditions, the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, was performing Salat (prayer) when a caravan passed by. They stopped by the companions of the Messenger of Allah and asked them about him (the Messenger of Allah), prayed, praised and said, ‘Were we not in a hurry we would have waited for the Messenger of Allah, so convey our Salam (the phrase of offering greeting of peace) to him (the Messenger of Allah); and they left. The Messenger of Allah became angry and said to them, ‘A caravan stops by and asks you about me. They ask you to convey their Salam (the phrase of offering greeting of peace) to me but you do not show any courtesy and invite them for food. Had beloved Ja‘far been present, he would not send the people away without inviting them for food.’”

When your brother (in belief) comes to your house, offer him food, if he did not want, then offer him water and if he did not want water offer him wudu (to wash his face or perfume).’”
