Sayyidina Anas ibn Maalik reported that the Prophet visited a sick man who had gone weak and fatigued looking like the young of a bird. He asked him, ‘Do you not pray to Your Lord to give You health?” He said, “I used to pray, “0 Allah whatever punishment You will give me in the Hereafter, hasten it for me in this workd.” The Prophet said, ‘Glory to Allah! You do not have the strength nor can you endure it. Why do you not say:
0 Allah, give us good in this world and good in the Hereafter, and preserve us from the punishment of the fire?”
[Muslim 2688, Ahmed 12049]
