Abu Hurairah (May Allah be pleased with him) reported:
Abu Bakr asked, "O Messenger of Allah! Teach me some words so that I may recite them in the morning and in the evening." The Messenger of Allah (ﷺ) said, "Recite these words: 'Allahumma fatiras-samawati wal-ardi, 'alimal-ghaibi wash-shahadati, Rabba kulli shai'in wa malikahu. Ash- hadu an la ilaha illa Anta, a'udhu bika min sharri nafsi, wa sharrish- Shaitani wa shirkihi (O Allah! Creator of the heavens and the earth! Knower of the hidden and the exposed! Rubb of everything and every one. I bear witness that none has the right to be worshipped but You. I seek Your Protection from the evil of my own self from the evil of Satan and from the evil of Shirk to which he calls)."' The Messenger of Allah (ﷺ) added: "Recite these words in the morning and the evening and when you go to bed."[Abu Dawud and At- Tirmidhi].
