Seeking refuge with Allah (SWT) following every prayer

It was narrated that Muslim bin Abi Bakrah said: "My father used to say following every prayer: 'Allahumma inni a-udhu bika min al-kufri wal-faqri wa 'adhab al-qabr. ( O Allah, I seek refuge with You from Kufr, poverty, and the torment of the grave)' and I used to say them (these words). My father said: 'O my son, from whom did you learn this?' I said: 'From you. He said: "The Messenger of Allah (ﷺ) used to say them following the prayer.'"
