The man excused himself saying: “The milk that is in the breasts of these camels is for the breakfast of the people of the tribe and that, which lies in the container, is for their evening meals.” When he heard this, the Noble Prophet (s.a.w) prayed for him, saying: “O' Lord! Increase this person in wealth and children” - and the group continued on its way. A little later they came across another person, who too was engaged in feeding the camels.
When they requested him to provide them with some milk, he immediately milked the she-camels and poured all of the milk in the vessels of the Noble Prophet's (s.a.w). In addition to the milk he even presented them with a sheep and said: At the moment this is all I can offer but if you desire I shall arrange for more. The Noble Prophet (s.a.w) raised his holy hands and prayed: “O' Lord!
Grant him sustenance in a measure that is sufficient for him.” Astonished, his (s.a.w) companions said: “O' Prophet of Allah!
Grant Muhammad and his Progeny a sustenance in the measure that is just sufficient (for them).[^9] Charity Increases Sustenance Imam Sadiq (a.s) had many sons, one of whom was named Muhammad. Occasionally it would so happen that his income would exceed his expenses. Once, Imam Sadiq (a.s) inquired: “How much have you managed to save?” He replied: “Forty dinars.” The Imam (a.s) said: “Give it as charity in the way of Allah.
He said: This is all that I have with me and if I were to give this in charity there would be nothing left for me.” The Imam (a.s) insisted: “Go and give it in charity and Allah shall compensate it for you. Do you not know that for everything there is a key and the key to sustenance is charity?” Muhammad, heeding his father's advice, gave the forty dinars in charity. Hardly ten days had passed by since this episode when a sum of four thousand dinars was presented to the Imam (a.s).
