O, so and so, as you go to your bed; the rest of the hadith is the same but with this variation of wording that he said:" Thine Apostle whom Thou sent." If you die that night you would die on Fitra and if you get up in the morning you would get up with a bliss.
قَالَ رَسُولُ اللَّهِ ﷺ لِرَجُلٍ يَا فُلاَنُ إِذَا أَوَيْتَ إِلَى فِرَاشِكَ بِمِثْلِ حَدِيثِ عَمْرِو بْنِ مُرَّةَ غَيْرَ أَنَّهُ قَالَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ فَإِنْ مُتَّ مِنْ لَيْلَتِكَ مُتَّ عَلَى الْفِطْرَةِ وَإِنْ أَصْبَحْتَ أَصَبْتَ خَيْرًا
