Reciting Surat al-Ikhlas, al-Falaq, and al-Nas in morning and evening for protection

We went out on a rainy night and in intense darkness, looking for the Messenger of Allah ﷺ to lead us in prayer. We found him, and he said, "Have you prayed?" But I said nothing. Then he said, "Say." But I said nothing. Then he said, "Say." But I said nothing. Then he said, "Say." So I said, "O Messenger of Allah ﷺ, what should I say?" He said, "Recite: "Say, He is Allah, One," and the Muawwidhatayn when you enter the evening and when you enter the morning three times; it will suffice you against everything."

خَرَجْنَا فِي لَيْلَةِ مَطَرٍ وَظُلْمَةٍ شَدِيدَةٍ نَطْلُبُ رَسُولَ اللَّهِ ﷺ لِيُصَلِّيَ لَنَا، فَأَدْرَكْنَاهُ، فَقَالَ: «أَصَلَّيْتُمْ؟» فَلَمْ أَقُلْ شَيْئًا، فَقَالَ: «قُلْ»، فَلَمْ أَقُلْ شَيْئًا، ثُمَّ قَالَ: «قُلْ»، فَلَمْ أَقُلْ شَيْئًا، ثُمَّ قَالَ: «قُلْ». فَقُلْتُ: يَا رَسُولَ اللَّهِ ﷺ، مَا أَقُولُ؟ قَالَ: «﴿قُلْ هُوَ اللَّهُ أَحَدٌ﴾ وَالْمُعَوِّذَتَيْنِ، حِينَ تُمْسِي وَحِينَ تُصْبِحُ ثَلاَثَ مَرَّاتٍ، تَكْفِيكَ مِنْ كُلِّ شَىْءٍ».

"It was raining and dark, and we were waiting for the Messenger of Allah [SAW] to lead us in prayer. Then the Messenger of Allah [SAW] came out to lead us in prayer and he said: 'Say.' I said: 'What should I say?' He said: 'Say: He is Allah, (the) One and Al-Mu'awwadhatain in the evening and in the morning, three times, and that will suffice you against everything.'" (Using translation from Nasāʾī 5428)

أَصَابَنَا طَشٌّ وَظُلْمَةٌ فَانْتَظَرْنَا رَسُولَ اللهِ ﷺ لِيُصَلِّيَ لَنَا فَخَرَجَ فَأَخَذَ بِيَدِي فَقَالَ قُلْ فَسَكَتُّ قَالَ قُلْ قُلْتُ مَا أَقُولُ؟ قَالَ قُلْ هُوَ اللهُ أَحَدٌ وَالْمُعَوِّذَتَيْنِ حِينَ تُمْسِي وَحِينَ تُصْبِحُ ثَلَاثًا تَكْفِيكَ كُلَّ يَوْمٍ مَرَّتَيْنِ
