Nahj al-Balāgha
Hadith 700عِبَادَ اللهِ، إِنَّهُ لَيْسَ لِمَا وَعَدَ اللهُ مِنَ الْخَيْرِ مَتْرَكٌ، وَلاَ فِيَما نَهَى عَنْهُ مِنَ الشَّرِّ مَرْغَبٌ. عِبَادَ اللهِ، احْذَرُوا يَوْماً تُفْحَصُ فِيهِ الاْعْمَالُ، وَيَكْثُرُ فِيهِ الزِّلْزَالُ، وَتَشِيبُ فِيهِ الاْطْفَالُ.
O creatures of Allāh! the good which Allāh has promised should not be abandoned and the evil from which He has refrained should not be coveted. O creatures of Allāh!, fear the day when actions will be reckoned; there will be much quaking and even children will get old.
