I was shown Lailat-ul-Qadr; then I was made to forget it, and saw that I was prostrating in water and clay in the morning of that (night). He (the narrator) said: There was a downpour on the twenty-third night and the Messenger of Allah ﷺ led us in prayer, and as he went back, there was a trace of water and clay on his forehead and on his nose. He (the narrator) said: 'Abdullah b. Unais used to say that it was the twenty-third (night). (Using translation from Muslim 1168)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ أُرِيتُ لَيْلَةَ الْقَدْرِ ثُمَّ أُنْسِيتُهَا وَأَرَانِي صَبِيحَتَهَا أَسْجُدُ فِي مَاءٍ وَطِينٍ قَالَ فَمُطِرْنَا لَيْلَةَ ثَلَاثٍ وَعِشْرِينَ فَصَلَّى بِنَا رَسُولُ اللهِ ﷺ ثُمَّ انْصَرَفَ وَإِنَّ أَثَرَ الْمَاءِ وَالطِّينِ لَعَلَى أَنْفِهِ وَجَبْهَتِهِ قَالَ وَكَانَ عَبْدُ اللهِ بْنُ أُنَيْسٍ يَقُولُ ثَلَاثٌ وَعِشْرُونَ لَفْظُ حَدِيثِ أَبِي عَبْدِ اللهِ  

[Machine] We were in the desert and we said, "If we proceed with our people, it will be difficult for us, and if we leave them behind, they will face hardship." He then sent me, and I was the youngest among them, to the Messenger of Allah, ﷺ . So, I mentioned their statement to him, and he commanded us to spend the night of the twenty-third (of Ramadan) in prayer. Ibn Al-Hadad said, "Muhammad ibn Ibrahim exerted himself on that night."  

كُنَّا بِالْبَادِيَةِ فَقُلْنَا إِنْ قَدِمْنَا بِأَهْلِينَا شَقَّ عَلَيْنَا وَإِنْ خَلَّفْنَاهُمْ أَصَابَتْهُمْ ضِيقَةٌ قَالَ فَبَعَثُونِي وَكُنْتُ أَصْغَرَهُمْ إِلَى رَسُولِ اللهِ ﷺ فَذَكَرْتُ لَهُ قَوْلَهُمْ فَأَمَرَنَا بِلَيْلَةِ ثَلَاثٍ وَعِشْرِينَ قَالَ ابْنُ الْهَادِ فَكَانَ مُحَمَّدُ بْنُ إِبْرَاهِيمَ يَجْتَهِدُ تِلْكَ اللَّيْلَةَ  

I said to the Messenger of Allah: I have a place in the desert where I live and in which I pray, with the praise of Allah; but give me command about a night when I come to this mosque. He replied: Come on the twenty third night. I (a sub-narrator, Muhammad ibn Ibrahim) said to his (Abdullah ibn Unays's) son: How would your father act? He replied: He used to enter the mosque when he had offered the afternoon prayer, and did not leave it for any purpose till he prayed the morning prayer. Then when he had prayed the morning prayer, he found his riding beast at the door of the mosque, mounted it and got back to his desert. (Using translation from Abū Dāʾūd 1380)   

قُلْتُ يَا رَسُولَ اللهِ إِنَّ لِي بَادِيَةً أَكُونُ فِيهَا وَأَنَا أُصَلِّي فِيهَا بِحَمْدِ اللهِ فَمُرْنِي بِلَيْلَةٍ أَنْزِلُهَا إِلَى هَذَا الْمَسْجِدِ فَقَالَ انْزِلْ لَيْلَةَ ثَلَاثٍ وَعِشْرِينَ فَقُلْتُ لِابْنِهِ فَكَيْفَ كَانَ أَبُوكَ يَصْنَعُ؟ قَالَ كَانَ يَدْخُلُ الْمَسْجِدَ إِذَا صَلَّى الْعَصْرَ فَلَا يَخْرُجُ مِنْهُ لِحَاجَةٍ حَتَّى يصَلِّيَ الصُّبْحَ فَإِذَا صَلَّى الصُّبْحَ وَجَدَ دَابَّتَهِ عَلَى بَابِ الْمَسْجِدِ فَجَلَسَ عَلَيْهَا فَلَحِقَ بِبَادِيَتِهِ  

[Machine] The Messenger of Allah ﷺ said, "How many days of the month have passed?" They said, "Twenty-two have passed and eight remain." He said, "No, twenty-two have passed and seven remain. Seek it tonight."  

قَالَ رَسُولُ اللهِ ﷺ كَمْ مَضَى مِنَ الشَّهْرِ قَالُوا مَضَى اثْنَتَانِ وَعِشْرُونَ وَبَقِيَ ثَمَانٍ فَقَالَ بَلْ مَضَى اثْنَتَانِ وَعِشْرُونَ وَبَقِيَ سَبْعٌ اطْلُبُوهَا اللَّيْلَةَ  

[Machine] We were with the Messenger of Allah ﷺ when they mentioned the Night of Decree. The Messenger of Allah ﷺ said, "How many days of the month have passed?" They said, "Twenty-two days have passed and there are eight days remaining." He said, "Twenty-two days have passed and there are seven left. The month is twenty-nine days, so seek it on the night." Abu Nu'aim confirmed this.  

كُنَّا عِنْدَ رَسُولِ اللهِ ﷺ فَذَكَرُوا لَيْلَةَ الْقَدْرِ فَقَالَ رَسُولُ اللهِ ﷺ كَمْ مَضَى مِنَ الشَّهْرِ؟ قَالُوا اثْنَتَانِ وَعِشْرُونَ وَبَقِيَ ثَمَانٍ قَالَ مَضَى اثْنَتَانِ وَعِشْرُونَ وَبَقِيَ سَبْعٌ الشَّهْرُ تِسْعٌ وَعِشْرُونَ فَالْتَمِسُوهَا اللَّيْلَةَ فَقَالَ أَبُو نُعَيْمٍ نَعَمْ  

[Machine] The Messenger of Allah, ﷺ , asked: "How many days are left of the month?" We replied: "Twenty-two have passed and there are eight left." He said: "Twenty-two have passed and there are seven left. Seek it on the twenty-ninth night."  

رَسُولُ اللهِ ﷺ كَمْ مَضَى مِنَ الشَّهْرِ؟ قُلْنَا اثْنَتَانِ وَعِشْرُونَ وَبَقِيَ ثَمَانٍ فَقَالَ مَضَى اثْنَتَانِ وَعِشْرُونَ وَبَقِيَ سَبْعٌ اطْلُبُوهَا اللَّيْلَةَ الشَّهْرُ تِسْعٌ وَعِشْرُونَ  

[Machine] Abdullah said, "Seek the Night of Qadr on the seventeenth, nineteenth, or twenty-first night of the lunar month."  

قَالَ عَبْدُ اللهِ تَحَرَّوْا لَيْلَةَ الْقَدْرِ لَيْلَةَ سَبْعَةَ عَشَرَ صَبِيحَةَ بَدْرٍ أَوْ إِحْدَى وَعِشْرِينَ أَوْ ثَلَاثًا وَعِشْرِينَ  

The Messenger of Allah ﷺ said to us: Seek it (laylat al-Qadr) on the seventeenth night of Ramadan, and on the twenty first night, and on the twenty-third night. He then kept silence. (Using translation from Abū Dāʾūd 1384)   

قَالَ رَسُولُ اللهِ ﷺ اطْلُبُوهَا لَيْلَةَ سَبْعَ عَشْرَةَ مِنْ رَمَضَانَ وَلَيْلَةَ إِحْدَى وَعِشْرِينَ وَلَيْلَةَ ثَلَاثٍ وَعِشْرِينَ ثُمَّ سَكَتَ
