The Messenger of Allah used to teach his Companions, saying: “When one of you reached the morning, then let him say: ‘O Allah, by You we enter the morning, and by You we enter the evening, and be You we live, and by You we died, and to You is the Return (Allahumma Bika Asbahna Wa Bika Amsaina Wa Bika Nahya Wa Bika Namutu Wa Ilaikal-Masir) And when he reaches the evening let him say: ‘O Allah, by You we enter the evening, and by You we enter the morning, and by You we live, and by You we die, and to You is the Resurrection (Allahumma Bika Amsaina Wa Bika Asbahna Wa Bika Nahya Wa Bika Namutu wa Ilaikan-Nushur).’”

“Abu Bakr said: ‘O Messenger of Allah, command me with something that I may say when I reach morning and evening.’ He said: ‘Say: “O Allah Knower of the Unseen and the Seen, Originator of the heavens and the earth, Lord of everything and its Possessor, I bear witness that there is none worthy of worship except You, I seek refuge from You from the evil of my soul and from the evil of Shaitan and his Shirk (Allahumma `Aalimal-Ghaibi Wash-Shahadati Fatiras-Samawati Wal-Ard, Rabba Kulli Shai’in Wa Malikahu, Ash-hadu An La Ilaha Illa Anta, A’udhu Bika Min Sharri Nafsi Wa Min Sharrish-Shaitani Washirkihi).’” He said: ‘Say it when you reach morning, and evening, and when you go to bed.’”
