حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا سُفْيَانُ، عَنِ ابْنِ جُرَيْجٍ، عَنْ سُلَيْمَانَ الأَحْوَلِ، خَالِ ابْنِ أَبِي نَجِيحٍ عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي سَعِيدٍ،‏.‏ قَالَ سُفْيَانُ وَحَدَّثَنَا مُحَمَّدُ بْنُ عَمْرٍو، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي سَعِيدٍ،‏.‏ قَالَ وَأَظُنُّ أَنَّ ابْنَ أَبِي لَبِيدٍ، حَدَّثَنَا عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي سَعِيدٍ ـ رضى الله عنه ـ قَالَ اعْتَكَفْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم الْعَشْرَ الأَوْسَطَ، فَلَمَّا كَانَ صَبِيحَةَ عِشْرِينَ نَقَلْنَا مَتَاعَنَا فَأَتَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ مَنْ كَانَ اعْتَكَفَ فَلْيَرْجِعْ إِلَى مُعْتَكَفِهِ فَإِنِّي رَأَيْتُ هَذِهِ اللَّيْلَةَ، وَرَأَيْتُنِي أَسْجُدُ فِي مَاءٍ وَطِينٍ ‏"‏‏.‏ فَلَمَّا رَجَعَ إِلَى مُعْتَكَفِهِ، وَهَاجَتِ السَّمَاءُ، فَمُطِرْنَا فَوَالَّذِي بَعَثَهُ بِالْحَقِّ لَقَدْ هَاجَتِ السَّمَاءُ مِنْ آخِرِ ذَلِكَ الْيَوْمِ، وَكَانَ الْمَسْجِدُ عَرِيشًا، فَلَقَدْ رَأَيْتُ عَلَى أَنْفِهِ وَأَرْنَبَتِهِ أَثَرَ الْمَاءِ وَالطِّينِ‏.‏
