Jami` at-Tirmidhi 3503

Muslim bin Abi Bakrah said:“My father heard me while I was saying: “O Allah, I seek refuge in You from sadness and laziness and the punishment of the grave (Allāhumma, innī a`ūdhu bika minal-hammi wal-kasali wa `adhābil-qabr).’ He said: ‘O my son, from who did you hear this?’” He said: “I said: ‘I heard you saying them.’ He said: ‘Stick to them, for indeed, I heard the Messenger of Allah (ﷺ) saying them.’”
