Narrated Nafi`:
وَعَنْ نَافِعٍ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، كَانَ يُسَلِّمُ بَيْنَ الرَّكْعَةِ وَالرَّكْعَتَيْنِ فِي الْوِتْرِ، حَتَّى يَأْمُرَ بِبَعْضِ حَاجَتِهِ.
Hadrat Abdullah bin Umer رضی اللہ عنہما that he would perform the salutation between one and two units of Witr; and pass orders to fulfil any of his needs.
