Do not get used to observe prayer at the time of the rising sun and at the time of its setting and (exhorted the Muslims) to pray at their times. (Using translation from Muslim 833b)
أَنَّهَا قَالَتْ لَمْ يَدَعْ رَسُولُ اللهِ ﷺ الرَّكْعَتَيْنِ بَعْدَ الْعَصْرِقَالَتْ وَقَالَ رَسُولُ اللهِ ﷺ وَلَا تَتَحَرَّوْا طُلُوعَ الشَّمْسِ وَلَا غُرُوبَهَا فَتُصَلُّوا عِنْدَ ذَلِكَ
