Allah's Messenger (ﷺ) used to invoke (Allah): "Allahumma ini a`udhu bika min 'adhabi-l-Qabr, wa min 'adhabi-nnar, wa min fitnati-l-mahya wa-lmamat, wa min fitnati-l-masih ad-dajjal. (O Allah! I seek refuge with you from the punishment in the grave and from the punishment in the Hell fire and from the afflictions of life and death, and the afflictions of Al-Masih Ad-Dajjal."
Sahih al-Bukhari Book 23, Hadith 129
← Previous Hadith (From the daughter of Khalid bin Sa id bin Al-`Asi) who said that she had heard the Prophet (ﷺ) seeking refuge with Allah from the punishment in the grave.

Sahih al-Bukhari Book 23, Hadith 128 Next Hadith → The Prophet (ﷺ) once passed by two graves and said, "They (the deceased persons in those graves) are being tortured not for a great thing to avoid." And then added, "Yes, (they are being punished for a big sin), for one of them used to go about with calumnies while the other never saved himself from being soiled with his urine." (Ibn `Abbas added): Then he took a green leaf of a date-palm) and split it into two pieces and fixed one piece on each grave and said, "May their punishment be abated till these (two pieces) get dry."
