Allah Causes Non-Muslims to Sin
Not content with merely preventing unbelievers from knowing the truth (which is enough to condemn them to Hell) the Quran says that a hateful Allah also causes unbelievers to commit the very sin that he will later punish them for:
And if Allah please He would certainly make you a single nation, but He causes to err whom He pleases and guides whom He pleases; and most certainly you will be questioned as to what you did (16:93)
Although Satan tempts Muslims, it is Allah himself who causes unbelievers to err.
Allah intentionally sends the people that he hates astray:
…and Allah sendeth him astray purposely, and sealeth up his hearing and his heart, and setteth on his sight a covering? Then who will lead him after Allah (hath condemned him)? Will ye not then heed? (45:23)
Allah even sends demons to inspire unbelievers to commit further bad deeds (that he can later hold against them):
See thou not that We have set the Evil Ones on against the unbelievers, to incite them with fury? (19:83)
According to verse 3:54, Allah plots and schemes against unbelievers using deceit (the literal meaning of makara, the word used). Elsewhere, the Quran explains that Allah tricks unbelievers into thinking that they are doing good deeds, when, in fact, they are merely deepening their own eternal punishment with bad deeds:
Allah recruits Satan to join Him into fooling unbelievers into thinking that they are doing good:
On the contrary their hearts became hardened, and Satan made their (sinful) acts seem alluring to them. (6:43)
The joke is on non-Muslims, of course, who will protest on Judgment Day that they did everything they thought was right – but are sent to Hell anyway:
Then would they offer submission (with the pretence), "We did no evil (knowingly)." (The angels will reply), "Nay, but verily Allah knows all that ye did; "So enter the gates of Hell, to dwell therein. (16:28-29)
