Wheat is an annual grass seed. It is a winter crop that originated in the Mediterranean basin countries. Wheat seeds are extracted from ears then ground to make flour used for baking. Wheat flour is an essential nutrient in the Global Agriculture and Food Security Program. It is indispensable and irreplaceable, as wheat seeds constitute a primary source of vitamins, minerals and fibers, and carbohydrates and protein are the most important nutrients in wheat.
Wheat is mentioned in the following hadith reported by Mohammad ibn Abi-il-Mujalid who said: “Abdullah ibn Shaddad and Abu Burdah sent me to Abdullah ibn Abi-Awfa and told me, “Ask him whether at the time of Prophet Muhammad, peace be upon him, the Companions of the
Prophet used to make advance payment for wheat.” Abdullah said, “We
used to make advance payments to the peasants of the Levant for wheat, barley and oil for a specified measure and a specified delivery time.” I
asked, “To the person who possessed the crop?” He answered, “We did not
ask about that.” Then, they sent me to Abdur-Rahman ibn Abza and I
asked him about the same thing. He answered, “The Companions of Prophet Muhammad, peace be upon him, used to make advance payments at the time of Prophet Muhammad, peace be upon him, and we did not ask them whether they had the crops or not.”’ (Sahih Al-Bukhari)
