﴿ فَٱصْفَحْ عَنْهُمْ وَقُلْ سَلَٰمٌۭ ۚ فَسَوْفَ يَعْلَمُونَ ﴾

“Yet bear thou with them, and say, “Peace [be upon you]!” - for in time they will come to know [the truth].”

God exalted be He says Then disregard them leave them be and say ‘Peace!’ I will stay away from you — this was revealed before he was commanded to fight them. For they will soon come to know ya‘lamūna may also be read as second person plural ta‘lamūna ‘you will come to know’ meant to threaten them.
