Make the most of five things before five things
Prophet Muhammad (peace be upon him) says:
O ‘Abādhar! Make the most of five things before five things: youth before oldness, health before illness, wealth before neediness, leisure before occupation, and life before death.
یا أَباذَرٍّ اغْتَنِمْ خَمساً قَبلَ خَمسٍ: شَبابَکَ قَبلَ هَرَمِکَ، وَصِحَّتَکَ قَبلَ سُقمِکَ، وَغِناکَ قَبلَ فَقرِکَ، وَفَراغَکَ قَبلَ شُغلِکَ، وَحَیاتَکَ قَبلَ مَوتِکَ.
