‘Abdullah b. Khubaib (RA) said: We went out one rainy and intensely dark night to look for Allah’s Messenger (ﷺ), and when we caught up on him, he (ﷺ) said to me, “Say.” I asked him what I was to say, and he replied, “If you recite ‘Say, He is God, One’ (Surah Al-Ikhlas) and al-Mu'awidhatān (The last 3 sūras of the Qur’ān) three times morning and evening, they will serve you for every purpose.” Tirmidhī, Abū Dāwūd and Nasā’i transmitted it.
