'A'isha reported that 'Umar misconstrued the fact that the Messenger of Allah ﷺ had prohibited the observance of prayer at the time of the rising sun and at the time of its setting. (Using translation from Muslim 833a)
عَائِشَةُ أُوِهَمَ عُمَرَ إِنَّمَا نَهَى رَسُولُ اللهِ ﷺ أَنْ يُتَحَرَّى طُلُوعُ الشَّمْسِ أَوْ غُرُوبُهَا
