﴿ إِلَىٰ يَوْمِ ٱلْوَقْتِ ٱلْمَعْلُومِ ﴾

“till the Day the time whereof is known [only to Me].””

In the present world of trial, Satan has been given every opportunity to misguide man. But Satan can do so only till Doomsday arrives. When the Day of Judgement tears apart the veil of falsehood, everything will become plain and clear. Thereafter, there will neither be anybody who can deceive nor anybody who can be deceived.
