Foods are of different shapes and taste, so who put therein beauty, sweetness, health, and cure? Allah (may He be Exalted) says: "And eat and drink but waste not by extravagance" [Surat Al A`raf: 31].
Allah (may He be Exalted) says: "And in the earth are neighbouring tracts, and gardens of vines, and green crops (fields), and date-palms, growing into two or three from a single stem root, or otherwise (one stem root for every palm), watered with the same water; yet, some of them We make more excellent than others to eat. Verily, in these things there are Ayât (proofs, evidences, lessons, signs) for the people who understand." [Surat Ar-Ra`d: 4].
Allah (Exalted be He) says: "And it is He Who produces gardens trellised and untrellised, and date-palms, and crops of different shape and taste (their fruits and their seeds) and olives, and pomegranates, similar (in kind) and different (in taste)." [Surat Al An`am: 141].
From one earth and soil Allah created all kinds of food with different colors, shapes, and taste, so who put therein beauty, sweetness, health, and cure? Who is the one who inspired bees to eat from all fruits then get out pure honey palatable to drinkers. ""Then, eat of all fruits, and follow the ways of your Lord made easy (for you)." There comes forth from their bellies, a drink of varying colour wherein is healing for men. Verily, in this is indeed a sign for a people who think." [Surat An-Nahl: 69].
From a single cell Allah created the children of Adam, and made for them hearings, sights, sensual, dynamic, digestive, and circulatory systems besides thousand of graces all these blessings to worship, unify, and thank Him and to bear the trust which Allah burdened us with to offer goodness to the people, help the needy, and do all good and charitable work because Allah (may He be Exalted) commanded us with benevolence and perfection in everything and commanded us to work and perfect our work because work is kind of worship. The Messenger of Allah (peace be upon him) loved the hands that do good. Allah (Exalted be He) says: "Indeed there was for Saba' (Sheba) a sign in their dwelling-place - two gardens on the right hand and on the left; (and it was said to them:) "Eat of the provision of your Lord, and be grateful to Him."" [Surat Saba': 15].
