Surah 11:114
"And observe the prayer at the two ends of the day and at the approach of the night. Surely good (deeds) take away evil (ones). That is a reminder to the mindful."
11.114 – And observe the prayer at the two ends of the day and at the approach of the night
The Quran does not specify five times of ritual prayer (ṣalāh), but rather three. See the comment at a similar verse, 17.78.
