[Machine] The companions of the Messenger of Allah ﷺ were discussing the Night of Decree (Laylat al-Qadr). Ubayy said, "By the One whom there is no god but Him, I know which night it is. It is the night that the Messenger of Allah ﷺ informed us about, the night that falls on the twenty-seventh of Ramadan. The sign of that night is that the sun rises the following morning without any rays." Salamah bin Kuheil claimed that a visitor had informed him that he had observed this phenomenon for three years straight, from the first day of Ramadan to its last, and that he saw the dawn of the twenty-seventh morning without any rays.  

أحمد:٢١١٩٠حَدَّثَنَا مُصْعَبُ بْنُ سَلَّامٍ حَدَّثَنَا الْأَجْلَحُ عَنِ الشَّعْبِيِّ عَنْ زِرِّ بْنِ حُبَيْشٍ عَنْ أُبَيِّ بْنِ كَعْبٍ قَالَ

تَذَاكَرَ أَصْحَابُ رَسُولِ اللهِ ﷺ لَيْلَةَ الْقَدْرِ فَقَالَ أُبَيٌّ أَنَا وَالَّذِي لَا إِلَهَ غَيْرُهُ أَعْلَمُ أَيُّ لَيْلَةٍ هِيَ هِيَ اللَّيْلَةُ الَّتِي أَخْبَرَنَا بِهَا رَسُولُ اللهِ ﷺ لَيْلَةَ سَبْعٍ وَعِشْرِينَ تَمْضِي مِنْ رَمَضَانَ وَآيَةُ ذَلِكَ أَنَّ الشَّمْسَ تُصْبِحُ الْغَدَ مِنْ تِلْكَ اللَّيْلَةِ تَرَقْرَقُ لَيْسَ لَهَا شُعَاعٌ فَزَعَمَ سَلَمَةُ بْنُ كُهَيْلٍ أَنَّ زِرًّا أَخْبَرَهُ أَنَّهُ رَصَدَهَا ثَلَاثَ سِنِينَ مِنْ أَوَّلِ يَوْمٍ يَدْخُلُ رَمَضَانُ إِلَى آخِرِهِ فَرَآهَا تَطْلُعُ صَبِيحَةَ سَبْعٍ وَعِشْرِينَ تَرَقْرَقُ لَيْسَ لَهَا شُعَاعٌ
