Say: Who hath forbidden the beautiful (gifts) of Allah, which He hath produced for His servants, and the things, clean and pure, (which He hath provided) for sustenance? Say: They are, in the life of this world, for those who believe, (and) purely for them on the Day of Judgment. Thus do We explain the signs in detail for those who understand. 32 Tell them: "My Lord has forbidden repugnant acts, whether open or disguised, sin and unjust oppression, associating others with God, of which He has sent down no authority, and saying things of God of which you have no knowledge." 33 And every group has a promise; so when its promise comes, it cannot be postponed for a moment or brought forward. 34 Children of Adam, when Messengers from among your own people come to you to preach My revelations, those who choose piety and reform themselves will have nothing to fear nor will they be grieved. 35 But those who reject Our signs and treat them with arrogance,- they are companions of the Fire, to dwell therein (for ever). 36 Who is more unjust than one who invents a lie against Allah or rejects His Signs? For such, their portion appointed must reach them from the Book (of decrees): until, when our messengers (of death) arrive and take their souls, they say: "Where are the things that ye used to invoke besides Allah?" They will reply, "They have left us in the lurch," And they will bear witness against themselves, that they had rejected Allah. 37 [Allah] will say, "Enter among nations which had passed on before you of jinn and mankind into the Fire." Every time a nation enters, it will curse its sister until, when they have all overtaken one another therein, the last of them will say about the first of them "Our Lord, these had misled us, so give them a double punishment of the Fire. He will say, "For each is double, but you do not know." 38 And the foremost of them will say to the last of them: So you have no preference over us; therefore taste the chastisement for what you earned. 39
