"The Messenger of Allah [SAW] said to me: 'Say.' I said: 'What should I say?' He said: 'Say: He is Allah (the) One,' 'Say: I seek refuge with (Allah) the Lord of the daybreak,' 'Say: I seek refuge with (Allah) the Lord of mankind.' The Messenger of Allah [SAW] recited them, then he said: 'The people have never recited anything like them, or the people have never sought refuge (with Allah) by means of anything like them.'" (Using translation from Nasāʾī 5431)  

قَالَ لِي رَسُولُ اللهِ ﷺ «يا عُقْبَةُ قُلْ» قُلْتُ مَا أَقُولُ؟ قَالَ قُلْ هُوَ اللهُ أَحَدٌ ثُمَّ قَالَ قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ قُلْ أَعُوذُ بِرَبِّ النَّاسِ فَقَرَأَهُنَّ رَسُولُ اللهِ ﷺ ثُمَّ قَالَ «لَمْ يَتَعَوَّذِ النَّاسُ بِمِثْلِهِنَّ» أَوْ «لَا يَتَعَوَّذُ النَّاسُ بِمِثْلِهِنَّ»
