(Ambiya') 21 : 109
فَإِنْ تَوَلَّوْا فَقُلْ آذَنْتُكُمْ عَلَىٰ سَوَاءٍ ۖ وَإِنْ أَدْرِي أَقَرِيبٌ أَمْ بَعِيدٌ مَا تُوعَدُونَ
Then if they are turning away, you say: "I have announced to you everything all alike; and I don’t know whether what you are promised with is near or far”.
The duty of Messenger and believer is only to convey the Lord’s Message Adhikr to the entire mankind, whereas the duty of Reckoning is upon the Impartial Lord as explained in verses 5: 67 and 13: 40. As there is no group of believers anywhere in the world, the odd believer follows the mode of prayer and lifestyle as explained in verses 7: 205-206. See explanation 7: 187-188; 18: 110 and 21: 35-38.
