(Az-Zukhuruf) 43 : 89
فَاصْفَحْ عَنْهُمْ وَقُلْ سَلَامٌ ۚ فَسَوْفَ يَعْلَمُونَ
Then you turn away from them; and you say “Peace”; then they will know later.
As explained in verses 7: 52-53, this verse commands the Messenger and thereby the believers to say the disbelievers who read the verses of Lord’s Book, but lead a life against the teaching of It as: “You can go, you will suffer the consequence of rejecting the Book when the prophecy of It will come in force”. Since there is no any group of believers anywhere in the world, the odd believer who testifies Adhikr should follow the life way and mode of prayer as explained in verses 7: 205-206. See explanation 9: 80-82; 25: 63, 65-66; and 41: 53-54
