كَانَ عَبْدُ اللَّهِ بْنُ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا يَقُولُ: إذَا أَمْسَيْتَ فَلَا تَنْتَظِرْ الصَّبَاحَ، وَإِذَا أَصْبَحْتَ فَلَا تَنْتَظِرْ الْمَسَاءَ، وَخُذْ مِنْ صِحَّتِك لِمَرَضِك، وَمِنْ حَيَاتِك لِمَوْتِك

‘Abdullāh ibn ‘Umar (may Allāh be pleased with them both) said:

“In the evening do not expect [to live until] the morning, and in the morning do not expect [to live until] the evening. Take [advantage of] your health before times of sickness, and [take advantage of] your life before your death.”
