Take account of yourselves before you are taken to account.
حاسبوا أنفسكم قبل أن تحاسبوا، وتزيّنوا للعرض الأكبر
Hâsibû enfüseküm kable en tühâsebû, ve tezeyyenû li'l-arzi'l-ekber
Tirmidhi, al-Sunan, Sifat al-Qiyama 25 (after hadith no. 2459, with the note “yurwa an Umar”); also Ibn al-Mubarak, al-Zuhd, no. 306; Ibn Abi Shayba, al-Musannaf, no. 35600.
The day of reckoning will come.
Umar does not advise waiting for it.
Open the ledger today.
With your own hand, before your own eyes.
A reckoning kept by another weighs heavy.
A reckoning you keep yourself makes you light.
People often look for it as a verse or a hadith.
The saying is Umar's.
