There was a sahabi who got very ill after he read a Surah I want to know the name of the Sahabi the name of the Surah too I don’t intent to do anything wrong it’s just a quiz I was asked I wonder what is the answer to it jazakallah
One very weak narration I came across is this mentioned in tafsir ibn Kathir:
Al-Hafiz Abu Bakr Ibn Abi Ad-Dunya recorded that Ja'far 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, (By At-Tur -surah 52-), until he reached the Ayah,
(Verily, the torment of your Lord will surely come to pass. There is none that can avert it. (52:7-8)) '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. (Source: qtafsir)
in this quote for whatever reasons the authors of qtafsir didn't display the full narrator chain of ibn abi ad-Dunya's narration which is quoted here in tafsir ibn Kathir beside a second narration. Salih al-Murri who has transmitted the word of Ja'far bin Zayd Al-'Abdi is considered as a weak narrator.
The second narration speaks about an illness of around twenty days. And again it was referred to 'Omar ibn al-Khattab, but doesn't seem to be authentic.
