The Prophet (blessings and peace of Allah be upon him) used to eat from what he earned with his hands. When he was young, he worked as a shepherd. It was narrated from Abu Hurayrah (may Allah be pleased with him) that the Prophet (blessings and peace of Allah be upon him) said: “Allah never sent any Prophet but he tended sheep.” His Companions said: Even you? He said: “Yes. I used to tend them in return for qaraareet for the people of Makkah.”
Narrated by al-Bukhaari, 2143.
Qareeraat refers to part of a dinar or dirham.
Our Prophet Muhammad (blessings and peace of Allah be upon him) also used to work in trade with his paternal uncle Abu Taalib and for Khadeejah (may Allah be pleased with her), as is well known in the Seerah (Prophet’s biography).
Then after that, Allah sufficed him with what He permitted to him of the fay’ (spoils) and ghaneemah (booty), which is the noblest of earnings.
Fay’ is that which is taken from the kuffaar without fighting.
Ghaneemah is that which is taken from the kuffaar by means of fighting.
It was narrated that Ibn ‘Umar (may Allah be pleased with him) said: The Messenger of Allah (sa) said: “I have been sent ahead of the Hour with the sword, until Allah alone is worshipped with no partner or associate, and my provision has been placed beneath the shade of my spear.”
