Sunan at-Tirmithiy كتاب الصوم باب ما جاء فى ليلة القدر
حَدَّثَنَا وَاصِلُ بْنُ عَبْدِ الأَعْلَى الْكُوفِىُّ حَدَّثَنَا أَبُو بَكْرِ بْنُ عَيَّاشٍ عَنْ عَاصِمٍ عَنْ زِرٍّ قَالَ قُلْتُ لأُبَىِّ بْنِ كَعْبٍ أَنَّى عَلِمْتَ أَبَا الْمُنْذِرِ أَنَّهَا لَيْلَةُ سَبْعٍ وَعِشْرِينَ قَالَ بَلَى أَخْبَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنَّهَا لَيْلَةٌ صَبِيحَتُهَا تَطْلُعُ الشَّمْسُ لَيْسَ لَهَا شُعَاعٌ. فَعَدَدْنَا وَحَفِظْنَا وَاللَّهِ لَقَدْ عَلِمَ ابْنُ مَسْعُودٍ أَنَّهَا فِى رَمَضَانَ وَأَنَّهَا لَيْلَةُ سَبْعٍ وَعِشْرِينَ وَلَكِنْ كَرِهَ أَنْ يُخْبِرَكُمْ فَتَتَّكِلُوا. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
Zirr Ibn-Hubaysh said, "I asked Ubaī Ibn-Ka'b, 'How did you know, Abā al-Munthir (1), that it (the Glorious Night of Determination) (2) is the twenty-seventh night [of Ramaḍān]?' He replied, 'Indeed, the Messenger of God, peace and blessings of God be upon him, informed us that, "On the morning following that night, the sun rises without emitting any rays." So we counted (3) and memorized it. By God, Ibn-Mas'ūd certainly knew that it is in Ramaḍān and that it is the twenty-seventh night; however, he disliked to inform you of that, lest you rely upon it (4).'"
(1) This was the nickname of Ubaī Ibn-Ka'b. (2) The night during which the Qur'ān was first revealed to prophet Muhammad. It occurs on one of the last ten nights of Ramadan, though God only knows which. The Qur'ān states that on this night, God determines the course of the world and all human affairs for the coming year. (3): To make sure of exactly which morning he had seen this sign. (4): And thus lose out on reward by limiting your performance of special voluntary acts of worship and supplications to that night alone.
