Al-Hafiz Abu Bakr Ibn Abi Ad-Dunya recorded that Jafar bin Zayd Al-`Abdi said,

"One night, in Al-Madinah, Umar went out investigating the welfare of Muslims and passed by the house of a man who was standing in voluntary prayer. Umar stood quietly, listening to his recitation; the man was reciting,
وَالطُّورِ
(By At-Tur), until he reached the Ayah,
إِنَّ عَذَابَ رَبِّكَ لَوَاقِعٌ
-
مَا لَهُ مِن دَافِعٍ
- (Verily, the torment of your Lord will surely come to pass. There is none that can avert it). Umar said, `By the Lord of the Ka`bah, this is a true vow.' Umar dismounted his donkey and sat next to a wall for a while. He then went back to his house and fell ill for a month. During his illness, the people would visit him, not knowing what caused his illness."

May Allah be pleased with Umar.
