All of Allah's statements are true, there is no doubt or cause for speculation about this fact, and all His commandments are pure justice, besides which there is no justice. All that He forbade is evil, for He only forbids what brings about evil consequences.Allah said in another Ayah,يَأْمُرُهُم بِالْمَعْرُوفِ وَيَنْهَـهُمْ عَنِ الْمُنْكَرِHe commands them with good; and forbids them from evil... (7:157) until the end of the Ayah.لااَّ مُبَدِّلِ لِكَلِمَاتِهِNone can change His Words.meaning, none can avert Allah's judgment whether in this life or the Hereafter.وَهُوَ السَّمِيعُAnd He is the All-Hearer,Hearing, His servants' statements,الْعَلِيمُThe All-Knower.of their activities and lack of activity, Who awards each according to their deeds
