"The Messenger of Allah ﷺ used to pray when I was lying in front of him as the bier is placed (in front of the Imam), and when he wanted to pray Witr he would nudge me with his foot." (Using translation from Nasāʾī 166)
إِنْ كَانَ لَرَسُولُ اللهِ ﷺ لَيُصَلِّي وَإِنِّي لَمُعْتَرِضَةٌ بَيْنَ يَدَيْهِ اعْتِرَاضَ الْجِنَازَةِ حَتَّى إِذَا أَرَادَ أَنْ يُوتِرَ مَسَّنِي بِرِجْلِهِ فَعَرَفْتُ أَنَّهُ يُوتِرُ تَأَخَّرْتُ شَيْئًا مِنْ بَيْنِ يَدَيْهِ
