حَدَّثَنَا سَعِيدُ بْنُ عُفَيْرٍ ، قَالَ : حَدَّثَنِي اللَّيْثُ ، قَالَ : حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ خَالِدِ ، عَنِ ابْنِ شِهَابٍ ، عَنْ سَالِمٍ ، قَالَ : صَلَّى بِنَا النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْعِشَاءَ فِي آخِرِ حَيَاتِهِ ، فَلَمَّا سَلَّمَ قَامَ ، فَقَالَ : " أَرَأَيْتَكُمْ لَيْلَتَكُمْ هَذِهِ ، فَإِنَّ رَأْسَ مِائَةِ سَنَةٍ مِنْهَا لَا يَبْقَى مِمَّنْ هُوَ عَلَى ظَهْرِ الْأَرْضِ أَحَدٌ " .
Narrated `Abdullah bin `Umar: Once the Prophet led us in the `Isha' prayer during the last days of his life and after finishing it (the prayer) (with Taslim) he said: "Do you realize (the importance of) this night?" Nobody present on the surface of the earth tonight will be living after the completion of one hundred years from this night."

Hadith 117
حَدَّثَنَا آدَمُ ، قَالَ : حَدَّثَنَا شُعْبَةُ ، قَالَ : حَدَّثَنَا الْحَكَمُ ، قَالَ : سَمِعْتُ سَعِيدَ بْنَ جُبَيْرٍ ، عَنِ ابْنِ عَبَّاسٍ ، قَالَ : " بِتُّ فِي بَيْتِ خَالَتِي مَيْمُونَةَ بِنْتِ الْحَارِثِ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، وَكَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِنْدَهَا فِي لَيْلَتِهَا ، فَصَلَّى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْعِشَاءَ ، ثُمَّ جَاءَ إِلَى مَنْزِلِهِ فَصَلَّى أَرْبَعَ رَكَعَاتٍ ، ثُمَّ نَامَ ، ثُمَّ قَامَ ، ثُمَّ قَالَ : نَامَ الْغُلَيِّمُ أَوْ كَلِمَةً تُشْبِهُهَا ، ثُمَّ قَامَ ، فَقُمْتُ عَنْ يَسَارِهِ فَجَعَلَنِي عَنْ يَمِينِهِ ، فَصَلَّى خَمْسَ رَكَعَاتٍ ، ثُمَّ صَلَّى رَكْعَتَيْنِ ، ثُمَّ نَامَ حَتَّى سَمِعْتُ غَطِيطَهُ أَوْ خَطِيطَهُ ، ثُمَّ خَرَجَ إِلَى الصَّلَاةِ " .
Narrated Ibn `Abbas: I stayed overnight in the house of my aunt Maimuna bint Al-Harith (the wife of the Prophet ) while the Prophet was there with her during her night turn. The Prophet offered the `Isha' prayer (in the mosque), returned home and after having prayed four rak`at, he slept. Later on he got up at night and then asked whether the boy (or he used a similar word) had slept? Then he got up for the prayer and I stood up by his left side but he made me stand to his right and offered five rak`at followed by two more rak`at. Then he slept and I heard him snoring and then (after a while) he left for the (Fajr) prayer.
