Recite Sūrat al-Ikhlāṣ, al-Falaq and al-Nās three times each in the morning and the evening. The Prophet ﷺ told ʿAbdullāh ibn Khubayb: “Say ‘Qul huwa-llāhu aḥad’ and the two sūrahs of refuge, three times when you reach evening and morning — they will suffice you against everything.” (Abū Dāwūd & Tirmidhī — ḥasan).
العربية: عن عبد الله بن خُبيبٍ رضي الله عنه أنّ النبيّ ﷺ قال: «قُل هو الله أحد والمعوّذتين حين تُمسي وتُصبح ثلاث مرات، تكفيك من كل شيء». (أبو داود والترمذي).
A few seconds, morning and evening — protection for your whole day and night.
