Hadith text
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)
Nafi bataate hain ke Abdullah bin Umar Witr ki namaz mein (pehli) do rakat aur (teesri) taaq rakat ke darmiyan Taslim kehte the, jab unhe kisi kaam se (beech mein) uthna hota.
