"Aishah told me to copy a Mushaf for her, and she said: 'When you reach this verse, call my attention: Guard strictly the Salawat especially the middle (Al-Wusta) Salah. [1] When I reached it, I called her attention and she dictated to me: 'Guard strictly the Salawat expecially the middle (Al-Wusta) Salah and the 'Asr prayer, and stand before Allah with obedience.' Then she said: 'I heard it from the Messenger of Allah ﷺ.'" [1] Al-Baqarah 2:238.  

عَنْ أَبِي يُونُسَ مَوْلَى عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ قَالَ أَمَرَتْنِي عَائِشَةُ أَنْ أَكْتُبَ لَهَا مُصْحَفًا فَقَالَتْ إِذَا بَلَغْتَ هَذِهِ الآيَةَ فَآذِنِّي { حَافِظُوا عَلَى الصَّلَوَاتِ وَالصَّلاَةِ الْوُسْطَى } فَلَمَّا بَلَغْتُهَا آذَنْتُهَا فَأَمْلَتْ عَلَىَّ حَافِظُوا عَلَى الصَّلَوَاتِ وَالصَّلاَةِ الْوُسْطَى وَصَلاَةِ الْعَصْرِ وَقُومُوا لِلَّهِ قَانِتِينَ ثُمَّ قَالَتْ سَمِعْتُهَا مِنْ رَسُولِ اللَّهِ ﷺ  

"They distracted us from Salatul-Wusta (the middle prayer) until the sun went down."  

عَنِ النَّبِيِّ ﷺ قَالَ شَغَلُونَا عَنِ الصَّلاَةِ الْوُسْطَى حَتَّى غَرَبَتِ الشَّمْسُ
