Overall meaning : Allah, Exalted be He, commands the Children of Adam to dress themselves in fine clothing that covers their nakedness and give them a decent appearance at every place of worship and in all the prayers, and to eat and drink of the wholesome things He has allowed them, but not to exceed the proper bounds by over-eating or violating His limits by consuming what He has forbidden, stating that He does not like those who exceed the proper bounds.
Then He instructs His Prophet to disapprovingly say to the ignorant Arabs who used to circumambulate the Ka’bah naked and deprive themselves of the good things He has permitted them: Who has forbidden you the beautiful things He has brought forth for His servants, such as the clothing which He has created for you, and who has forbidden you the pure, wholesome means of sustenance? 'Inform them,’ He further instructs him to say to them, 'that the fine clothing and the good kinds of provision are for the enjoyment of the believers, to be shared with unbelievers, in the life of the world, but they will be exclusively theirs on the Day of Judgement to the exclusion of the unbelievers.’ Just as He has explained such ruling in detail, so He always clarifies everything that needs explaining in the Qur’an for people to understand His revelations and benefit from them.
