Is Bodybuilding Permissible?
Yes. As a principle, other than the dietary restrictions whatever God has made impermissible falls in five broad categories. These categories are listed in the verse below. Once we understand this concept, a big majority of our haram/halal questions become self evident. Quran 7:33 Translation by Asad Say: “Verily, my Sustainer has forbidden only shameful deeds, be they open or secret, and [every kind of] sinning, and unjustified envy, and the ascribing of divinity to aught beside Him – since He has never bestowed any warrant therefor from on high and the attributing unto God of aught of which you have no knowledge.” For further details please see: Discussion 1749
