وَعَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يُسَلِّمُ بَيْنَ الرَّكْعَةِ وَالرَّكْعَتَيْنِ فِي الْوِتْرِ، حَتَّى يَأْمُرَ بِبَعْضِ حَاجَتِهِ.
Nafi 'told that 'Abdullah bin
'Umar used to say Taslim between (the first) two Rak 'at and (the third)
odd one in the Witr prayer, when he wanted to attend to a certain
matter (during that interval between the Rak 'at).
