قُلْ لَٓا اَمْلِكُ لِنَفْس۪ي ضَراًّ وَلَا نَفْعاً اِلَّا مَا شَٓاءَ اللّٰهُۜ لِكُلِّ اُمَّةٍ اَجَلٌۜ اِذَا جَٓاءَ اَجَلُهُمْ فَلَا يَسْتَأْخِرُونَ سَاعَةً وَلَا يَسْتَقْدِمُونَ

قُلْ لَٓا اَمْلِكُ لِنَفْس۪ي نَفْعاً وَلَا ضَراًّ اِلَّا مَا شَٓاءَ اللّٰهُۜ وَلَوْ كُنْتُ اَعْلَمُ الْغَيْبَ لَاسْتَكْثَرْتُ مِنَ الْخَيْرِۚ وَمَا مَسَّنِيَ السُّٓوءُ اِنْ اَنَا۬ اِلَّا نَذ۪يرٌ وَبَش۪يرٌ لِقَوْمٍ يُؤْمِنُونَ۟
