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." (Using translation from Nasāʾī 1728)
أَنَّ أَبَا مُوسَى كَانَ بَيْنَ مَكَّةَ وَالْمَدِينَةِ فَصَلَّى الْعِشَاءَ رَكْعَتَيْنِ ثُمَّ قَامَ فَصَلَّى رَكْعَةً أَوْتَرَ بِهَا فَقَرَأَ فِيهَا مِائَةَ آيَةٍ مِنَ النِّسَاءِ ثُمَّ قَالَ «مَا أَلَوْتُ أَنْ أَضَعَ قَدَمَيَّ حَيْثُ وَضَعَ رَسُولُ اللهِ ﷺ قَدَمَيْهِ وَأَنْ أَقْرَأُ بِمَا قَرَأَ بِهِ رَسُولُ اللهِ ﷺ»
