Abu Musa was between Makkah and Al-Madinah. He prayed 'Isha with two rak'ahs, then he stood and prayed one rak'ah of witr in which he recited one hundred verses from An-Nisa'. Then he said: "I tried my best to place my feet where the Messenger of Allah ﷺ placed his, and to recite what the Messenger of Allah ﷺ recited."  

أَنَّ أَبَا مُوسَى كَانَ بَيْنَ مَكَّةَ وَالْمَدِينَةِ فَصَلَّى الْعِشَاءَ رَكْعَتَيْنِ ثُمَّ قَامَ فَصَلَّى رَكْعَةً أَوْتَرَ بِهَا فَقَرَأَ فِيهَا بِمِائَةِ آيَةٍ مِنَ النِّسَاءِ ثُمَّ قَالَ مَا أَلَوْتُ أَنْ أَضَعَ قَدَمَىَّ حَيْثُ وَضَعَ رَسُولُ اللَّهِ ﷺ قَدَمَيْهِ وَأَنَا أَقْرَأُ بِمَا قَرَأَ بِهِ رَسُولُ اللَّهِ ﷺ
