My brother, Qatada bin An-Nau'man said, "A man performed the night prayer late at night in the lifetime of the Prophet ﷺ and he read: 'Say: He is Allah, (the) One,' (112.1) and read nothing besides that. The next morning a man went to the Prophet ﷺ ,~ and told him about that . (The Prophet ﷺ replied the same as (in Hadith 532) above.)
أَنَّ رَجُلاً قَامَ فِي زَمَنِ النَّبِيِّ ﷺ يَقْرَأُ مِنَ السَّحَرِ {قُلْ هُوَ اللَّهُ أَحَدٌ} لاَ يَزِيدُ عَلَيْهَا فَلَمَّا أَصْبَحْنَا أَتَى رَجُلٌ النَّبِيَّ ﷺ نَحْوَهُ
