Imam Sajjad (a.s) said: “God's Prophet passed by a cameleer. He sent someone to ask for some milk. The cameleer said: “What is in the pans is the dinner for the tribe and what is in their breasts is the breakfast for the tribe.” The Prophet (a.s) said: “O' God! Please increase his wealth and children.” Then he went on until they reached a shepherd. He sent someone to ask for some milk. The shepherd milked the sheep and gave all the milk in the pans plus that milk to the Prophet, along with one sheep and said: “This was what we had, and we will even give you more if you want.” God's Prophet (a.s) said: “O' God! Please give him only his sustenance.” One of the companions said: “O' Prophet of God! You prayed the way we all like to be prayed for, for the man who turned you down. But you prayed the way none of us like to be prayed for the man who fulfilled your needs.” God's Prophet (a.s) said: “What is available but is little is better than what is a lot but takes away one's peace of mind. O' God! Please provide for Muhammad and his family just their sustenance.”
