When there are two men and two women

It was narrated that Anas said:

"The Messenger of Allah (ﷺ) entered upon us and the only people present were myself, my mother, the orphan and Umm Harh, my maternal aunt. He said: 'Stand up and I will lead you in prayer.' It was not the time for a (prescribed) prayer. And he led us in prayer."

أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ سُلَيْمَانَ بْنِ الْمُغِيرَةِ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، قَالَ دَخَلَ عَلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَمَا هُوَ إِلاَّ أَنَا وَأُمِّي وَالْيَتِيمُ وَأُمُّ حَرَامٍ خَالَتِي فَقَالَ ‏

‏ قُومُوا فَلأُصَلِّيَ بِكُمْ ‏

‏ ‏.‏ قَالَ فِي غَيْرِ وَقْتِ صَلاَةٍ - قَالَ - فَصَلَّى بِنَا ‏.‏

It was narrated from Anas that he and the Messenger of Allah (ﷺ) and his mother, and his maternal aunt (were together). The Messenger of Allah (ﷺ) prayed, and he told Anas to stand on his right and his mother and maternal aunt behind them.

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدٌ، قَالَ حَدَّثَنَا شُعْبَةُ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ مُخْتَارٍ، يُحَدِّثُ عَنْ مُوسَى بْنِ أَنَسٍ، عَنْ أَنَسٍ، أَنَّهُ كَانَ هُوَ وَرَسُولُ اللَّهِ صلى الله عليه وسلم وَأُمُّهُ وَخَالَتُهُ فَصَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم فَجَعَلَ أَنَسًا عَنْ يَمِينِهِ وَأُمَّهُ وَخَالَتَهُ خَلْفَهُمَا ‏.‏
