The Three Quls
Morning, evening, before sleep
قُلْ هُوَ اللَّهُ أَحَدٌ ‧ قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ ‧ قُلْ أَعُوذُ بِرَبِّ النَّاسِ
Qul huwa Allāhu aḥad ‧ Qul aʿūdhu bi-Rabbi al-Falaq ‧ Qul aʿūdhu bi-Rabbi an-Nās.
"Sūrat al-Ikhlāṣ, al-Falaq, and an-Nās — the last three surahs of the Qurʾan. Recited three times each, morning and evening, as the Prophet ﷺ taught."
Source: Sunan Abī Dāwūd 5082
The Prophet ﷺ said: these three will protect you from everything.
