وَمَا يَسْتَوِى ٱلْأَعْمَىٰ وَٱلْبَصِيرُ وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّٰلِحَٰتِ وَلَا ٱلْمُسِىٓءُ ۚ قَلِيلًۭا مَّا تَتَذَكَّرُونَ
And the blind man and the seer are not equal, neither are those who believe and do good works (equal with) the evil-doer. Little do ye reflect!

Actions while Praying
Chapter: Thinking of something during As-Salat (the prayer)
Narrated Abu Huraira:
People say that I narrate too many narrations of the Prophet; once I met a man (during the lifetime of the Prophet) and asked him, "Which Sura did Allah's Messenger (ﷺ) s recite yesterday in the `Isha' prayer?" He said, "I do not know." I said, "Did you not attend the prayer?" He said, "Yes, (I did)." I said, "I know. He recited such and such Sura."
