The Hidden Words — Paragraph 32
Source (Arabic)
(٣١) ﴿ يَا ابْنَ الوُجُودِ ﴾
حاسِبْ نَفْسَكَ فِي كُلِّ يَوْمٍ مِنْ قَبْلِ أَنْ تُحَاسَبَ، لأَنَّ الْمَوْتَ يَأْتِيكَ بَغْتَةً وَتَقُومُ عَلَى الْحِسابِ فِي نَفْسِكَ.
Translation
(31) O SON OF BEING!
Bring thyself to account each day ere thou art summoned to a reckoning; for death, unheralded, shall come upon thee and thou shalt be called to give account for thy deeds.
