Anas bin Malik narrated that:
The Prophet (ﷺ) visited a man who was so emaciated that he had become like a baby bird. He (ﷺ) said to him: “And did you not used to supplicate? Did you not used to ask Your Lord for sound health?” He said: “I used to say: “O Allah, whatever You are going to punish me with in the Hereafter, then hasten it for me in this world.” So the Prophet (ﷺ) said: “Glory is to Allah, you are not capable of that” – or – “you are not able to stand that. Would you not say: ‘O Allah, give us good in this world, and good in the Hereafter, and spare us the punishment of the Fire (Allāhumma ātinā fid-dunyā ḥasanatan wa fil ākhirati ḥasanatan wa qinā `adhāban-nār).’”
