The most frequent invocation of The Prophet (ﷺ) was: "O Allah! Give to us in the world that which is good and in the Hereafter that which is good, and save us from the torment of the Fire." (2.201)
Sahih al-Bukhari Book 80, Hadith 84
← Previous Hadith The Prophet (ﷺ) said, "If anyone of you, when intending to have a sexual intercourse with his wife, says: 'Bismillah, Allahumma jannibna-sh-shaitan, wa jannibi-sh-shaitan ma razaqtana,' and if the couple are destined to have a child (out of that very sexual relation), then Satan will never be able to harm that child."

Sahih al-Bukhari Book 80, Hadith 83 Next Hadith → The Prophet (ﷺ) used to teach us these words as he used to teach us the Book (Qur'an): "O Allah! seek refuge with You from miserliness, and seek refuge with You from cowardice, and seek refuge with You from being brought back to (senile) geriatric old age, and seek refuge with You from the affliction of the world and from the punishment in the Hereafter."
