حَدَّثَنَا عُقْبَةُ بْنُ مُكْرَمٍ الْعَمِّىُّ وَأَبُو بَكْرِ بْنُ نَافِعٍ قَالاَ حَدَّثَنَا غُنْدَرٌ حَدَّثَنَا شُعْبَةُ عَنْ خَالِدٍ قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ الْحَارِثِ يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ أَنَّهُ أَمَرَ رَجُلاً إِذَا أَخَذَ مَضْجَعَهُ قَالَ « اللَّهُمَّ خَلَقْتَ نَفْسِى وَأَنْتَ تَوَفَّاهَا لَكَ مَمَاتُهَا وَمَحْيَاهَا إِنْ أَحْيَيْتَهَا فَاحْفَظْهَا وَإِنْ أَمَتَّهَا فَاغْفِرْ لَهَا اللَّهُمَّ إِنِّى أَسْأَلُكَ الْعَافِيَةَ ». فَقَالَ لَهُ رَجُلٌ أَسَمِعْتَ هَذَا مِنْ عُمَرَ فَقَالَ مِنْ خَيْرٍ مِنْ عُمَرَ مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم-. قَالَ ابْنُ نَافِعٍ فِى رِوَايَتِهِ عَنْ عَبْدِ اللَّهِ بْنِ الْحَارِثِ. وَلَمْ يَذْكُرْ سَمِعْتُ.

It was narrated from 'Abdullah bin 'Umar, that he ordered a man when he went to lie down, to say: "Allahumma khalaqta nafsi, wa anta tawaffaha, laka mamatuha wa mahyaha, in ahyaitaha fahfazha, wa in amattaha faghfir laha. Allahumma, (inni) as-alukal-'afiyah (O Allah, You have created my soul and it is for You to take it in death. Its death and its life are in Your Hand. If You cause it to live then protect it and if You cause it to die then forgive it. O Allah, I ask You to keep me safe and sound)." A man said to him: "Did you hear that from 'Umar?" He said: "From one who is better than 'Umar, from the Messenger of Allah (s.a.w)." Ibn Nafi' said in his report: "It was narrated from 'Abdullah bin Al-Harith," and he did not say: "I heard."
