[Machine] Ibn Abbas called upon Umar and the Companions of the Prophet ﷺ and asked them about the Night of Decree. They all agreed that it is in the last ten nights. So I said to Umar, "I know and I think which night it is." He asked, "Which night is it?" I said, "The seventh night, whether it passes or remains from the last ten nights." He asked, "How do you know?" I said, "I know because Allah created seven heavens and seven earths, and He created seven days, and surely time revolves in seven (days), and He created the human being with seven organs for eating and prostrating, and circumambulation (around the Kaaba) is seven, and there are seven mountains." So Umar said, "You have indeed realized something that we did not realize."
ابْنُ عَبَّاسٍ دَعَا عُمَرُ ؓ أَصْحَابَ النَّبِيِّ ﷺ فَسَأَلَهُمْ عَنْ لَيْلَةِ الْقَدْرِ فَأَجْمَعُوا أَنَّهَا فِي الْعَشْرِ الْأَوَاخِرِ فَقُلْتُ لِعُمَرَ إِنِّي لَأَعْلَمُ وَإِنِّي لَأَظُنُّ أِيَّ لَيْلَةٍ هِيَ قَالَ وَأِيُّ لَيْلَةٍ هِيَ؟ قُلْتُ سَابِعَةٌ تَمْضِي أَوْ سَابِعَةٌ تَبْقَى مِنَ الْعَشْرِ الْأَوَاخِرِ قَالَ وَمِنْ أَيْنَ تَعْلَمُ؟ قَالَ قُلْتُ خَلَقَ اللهُ سَبْعَ سَمَاوَاتٍ وَسَبْعَ أَرَضِينَ وَسَبْعَةَ أَيَّامٍ وَأَنَّ الدَّهْرَ يَدُورُ فِي سَبْعٍ وَخَلَقَ الْإِنْسَانَ فَيَأْكُلُ وَيَسْجُدُ عَلَى سَبْعَةِ أَعْضَاءٍ وَالطَّوَافُ سَبْعٌ وَالْجِبَالُ سَبْعٌ فَقَالَ عُمَرُ ؓ لَقَدْ فَطِنْتَ لِأَمْرٍ مَا فَطِنَّا لَهُ
