‘Abd-Allāh ibn ‘Umar, رضي الله عنهما said:
“If you reach the evening, do not await for the morning, and if you reach the morning, do not expect to reach the evening. Take benefit from your health [in preparation] for your sickness, and benefit from your life [to prepare] for your death.”
Saheeh al-Bukhāri 6416
O’ Allāh cure our sick and [all] the Muslims who are sick.
