God wants to make easy for you; and humankind was created weak.
Translation endnotes
[4:28] God created humans in an excellent design (32:7; 64:3; 82:7; 95:4), yet we humans may lower ourselves to the lowest level by following the teachings of devil (95:5). It is interesting to see the passive voice when degeneration of human nature is mentioned. The Quran does not say "we made humans weak," but it says, "humans were made weak." Thus, whenever our weakness, impatience, or pessimism is mentioned the passive voice is used (4:28; 21:37; 70:19). Through this peculiar language, the Best Designer and the Ultimate Creator who created is in best design with freedom of choice, reminds us the negative impact of wrong choices on our excellent design. See 57:22-23.
