Jami` at-Tirmidhi 3512

Anas bin Malik narrated that a man came to the Prophet (ﷺ) and said:“O Messenger of Allah, which supplication is the best?” He (ﷺ) said: “Ask Your Lord For Al-`Āfiyah and Al-Mu`āfāh in this world and in the Hereafter.” Then he came to him on the second day and said: “O Messenger of Allah, which supplication is the best?” So he (ﷺ) said to him similar to that. Then he came to him on the third day, so he (ﷺ) said to him similar to that. He (ﷺ) said: “So when you have been given Al-`Āfiyah in this world, and you have been given it in the Hereafter, then you have succeeded.”
