as for me am tall and built nd i have experienced many muslim being tall and slim..my question is did prophet muhammad (S.A.W) offered food for islam..
prophet Muhammad salla Allahou 3alayhi wa sallam said; "be hungry and you will be healthy".
and he also said; "we are a people who do not eat except when they are hungry, and if we ate we do not get full of stomach."
salla Allahou 3alayhi wa sallam also said; "the son of Adam did not fill a tank which is worst than his stomach, and if you got and should, then (make it) 1/3 for your food, and 1/3 for your drink, and 1/3 for your breath(air)."
and he also said; "enough for the son of Adam few peaces of bread to establish his power/strength."
honey in warm water in the morning eating odd numbers of dates, vinegar, dates in milk... from the preferable food of the prophet salla Allahou 3alayhi wa sallam.
