One day the Messenger of Allah ﷺ was sitting amongst us that he dozed off. He then raised his head smilingly. We said: What makes you smile. Messenger of Allah? He said: A Sura has just been revealed to me, and then recited: In the name of Allah, the Compassionate, the Merciful. Verily We have given thee Kauthar (fount of abundance). Therefore turn to thy Lord for prayer and offer sacrifice, and surely thy enemy is cut off (from the good). Then he (the Holy Prophet) said: Do you know what Kauthar is? We said: Allah and His Messenger know best. The Prophet ﷺ said: It (Kauthar) is a canal which my Lord, the Exalted and Glorious has promised me, and there is an abundance of good in it. It is a cistern and my people would come to it on the Day of Resurrection, and tumblers there would be equal to the number of stars. A servant would be turned away from (among the people gathered there). Upon this I would say: My Lord, he is one of my people, and He (the Lord) would say: You do not know that he innovated new things (in Islam) after you. Ibn Hujr made this addition in the hadith:" He (the Holy Prophet) was sitting amongst us in the mosque, and He (Allah) said: (You don't know) what he innovated after you"  

بَيْنَا رَسُولُ اللَّهِ ﷺ ذَاتَ يَوْمٍ بَيْنَ أَظْهُرِنَا إِذْ أَغْفَى إِغْفَاءَةً ثُمَّ رَفَعَ رَأْسَهُ مُتَبَسِّمًا فَقُلْنَا مَا أَضْحَكَكَ يَا رَسُولَ اللَّهِ قَالَ أُنْزِلَتْ عَلَىَّ آنِفًا سُورَةٌ فَقَرَأَ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ { إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ * فَصَلِّ لِرَبِّكَ وَانْحَرْ * إِنَّ شَانِئَكَ هُوَ الأَبْتَرُ} ثُمَّ قَالَ أَتَدْرُونَ مَا الْكَوْثَرُ فَقُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهُ نَهْرٌ وَعَدَنِيهِ رَبِّي ﷻ عَلَيْهِ خَيْرٌ كَثِيرٌ هُوَ حَوْضٌ تَرِدُ عَلَيْهِ أُمَّتِي يَوْمَ الْقِيَامَةِ آنِيَتُهُ عَدَدُ النُّجُومِ فَيُخْتَلَجُ الْعَبْدُ مِنْهُمْ فَأَقُولُ رَبِّ إِنَّهُ مِنْ أُمَّتِي فَيَقُولُ مَا تَدْرِي مَا أَحْدَثَتْ بَعْدَكَ زَادَ ابْنُ حُجْرٍ فِي حَدِيثِهِ بَيْنَ أَظْهُرِنَا فِي الْمَسْجِدِ وَقَالَ مَا أَحْدَثَ بَعْدَكَ  

"One day when he-the Prophet ﷺ- was still among us, he took a nap, then he raised his head, smiling. We said to him: 'Why are you smiling, O Messenger of Allah?' He said: 'Just now this Surah was revealed to me: In the Name of Allah, the Most Gracious, the Most Merciful. Verily, We have granted you (O Muahmmad) Al-Kawthar. Therefore turn in prayer to your Lord and sacrifice (to Him only). For he who hates you, he will be cut off.' Then he said: 'Do you know what Al-Kawthar is?' We said: 'Allah and His Messenger know best.' He said: 'It is a river that my Lord has promised me in Paradise. Its vessels are more than the number of the stars. My Ummah will come to me, then a man among them will be pulled away and I will say: "O Lord, he is one of my Ummah" and He will say to me: 'You do not know what he did after you were gone."  

بَيْنَمَا ذَاتَ يَوْمٍ بَيْنَ أَظْهُرِنَا يُرِيدُ النَّبِيَّ ﷺ إِذْ أَغْفَى إِغْفَاءَةً ثُمَّ رَفَعَ رَأْسَهُ مُتَبَسِّمًا فَقُلْنَا لَهُ مَا أَضْحَكَكَ يَا رَسُولَ اللَّهِ قَالَ نَزَلَتْ عَلَىَّ آنِفًا سُورَةُ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ { إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ * فَصَلِّ لِرَبِّكَ وَانْحَرْ * إِنَّ شَانِئَكَ هُوَ الأَبْتَرُ } ثُمَّ قَالَ هَلْ تَدْرُونَ مَا الْكَوْثَرُ قُلْنَا اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهُ نَهْرٌ وَعَدَنِيهِ رَبِّي فِي الْجَنَّةِ آنِيَتُهُ أَكْثَرُ مِنْ عَدَدِ الْكَوَاكِبِ تَرِدُهُ عَلَىَّ أُمَّتِي فَيُخْتَلَجُ الْعَبْدُ مِنْهُمْ فَأَقُولُ يَا رَبِّ إِنَّهُ مِنْ أُمَّتِي فَيَقُولُ لِي إِنَّكَ لاَ تَدْرِي مَا أَحْدَثَ بَعْدَكَ  

The Messenger of Allah ﷺ dozed for a short while and raised his smiling. He either said to them(people) or they said to him: Messenger of Allah! Why did you laugh? He said: A surah has been revealed to me just now, and then he recited: “In the name of Allah, Most Gracious. Most Merciful. To thee We have granted the fount (of abundance)” up to the end. When he recited, he asked: Do you know what al-kauthar is? They replied: Allah and his Apostle know best. He said: It is a river which my Lord, the Exalted, has promised me( to grant) in Paradise: there is abundance of good and upon it there is a pond which my people will approach on the Day of Resurrection. There are vessels as numerous as stars(in the sky).  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ أَغْفَى رَسُولُ اللَّهِ ﷺ إِغْفَاءَةً فَرَفَعَ رَأْسَهُ مُتَبَسِّمًا فَإِمَّا قَالَ لَهُمْ وَإِمَّا قَالُوا لَهُ يَا رَسُولَ اللَّهِ لِمَ ضَحِكْتَ فَقَالَ إِنَّهُ أُنْزِلَتْ عَلَىَّ آنِفًا سُورَةٌ فَقَرَأَ بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ {إِنَّا أَعْطَيْنَاكَ الْكَوْثَرَ} حَتَّى خَتَمَهَا فَلَمَّا قَرَأَهَا قَالَ هَلْ تَدْرُونَ مَا الْكَوْثَرُ قَالُوا اللَّهُ وَرَسُولُهُ أَعْلَمُ قَالَ فَإِنَّهُ نَهْرٌ وَعَدَنِيهِ رَبِّي ﷻ فِي الْجَنَّةِ وَعَلَيْهِ خَيْرٌ كَثِيرٌ عَلَيْهِ حَوْضٌ تَرِدُ عَلَيْهِ أُمَّتِي يَوْمَ الْقِيَامَةِ آنِيَتُهُ عَدَدُ الْكَوَاكِبِ
