[Machine] Sahl al-Ansari was a companion of the Prophet ﷺ and he had met the Prophet when he was fifteen years old. Ubayy ibn Ka'b told me that the fatwa they used to say, "Water from water is permissible," the Messenger of Allah ﷺ permitted it in the early days of Islam. Then he commanded us to perform ablution after it.  

سَهْلٌ الْأَنْصَارِيُّ وَكَانَ قَدْ أَدْرَكَ النَّبِيَّ ﷺ وَهُوَ ابْنُ خَمْسَ عَشْرَةَ فِي زَمَانِهِ حَدَّثَنِي أُبَيُّ بْنُ كَعْبٍ أَنَّ الْفُتْيَا الَّتِي كَانُوا يَقُولُونَ الْمَاءُ مِنَ الْمَاءِ رُخْصَةٌ كَانَ رَسُولُ اللهِ ﷺ رَخَّصَ بِهَا فِي أَوَّلِ الْإِسْلَامِ ثُمَّ أَمَرَنَا بِالِاغْتِسَالِ بَعْدَهَا  

[Machine] Narrated by Sahl bin Saad Al-Ansari, who reached the Prophet ﷺ when he was fifteen years old, he said: "Ubayy bin Ka'ab told me that the fatwa they used to give regarding their saying 'water from water is permissible' was the most lenient ruling that was issued in the early days of Islam. Then we were commanded to perform ablution after it."  

عَنْ سَهْلِ بْنِ سَعْدٍ الْأَنْصَارِيِّ وَقَدْ أَدْرَكَ النَّبِيَّ ﷺ وَهُوَ ابْنُ خَمْسَ عَشْرَةَ سَنَةً قَالَ حَدَّثَنِي أُبَيُّ بْنُ كَعْبٍ أَنَّ الْفُتْيَا الَّتِي كَانُوا يُفْتُونَ بِهَا فِي قَوْلِهِمْ الْمَاءُ مِنَ الْمَاءِ رُخْصَةٌ كَانَ أُرْخِصَ بِهَا فِي أَوَّلِ الْإِسْلَامِ ثُمَّ أُمِرْنَا بِالِاغْتِسَالِ بَعْدَهَا  

This hadith hilt been reported on the authority of Ma'mar with the same chain of transmitters. (Using translation from Muslim 2177e)   

وَأَخْبَرَنِي مَعْمَرٌ بِهَذَا الْإِسْنَادِ نَحْوَهُ  

[Machine] Sahl ibn Sa'd and he was fifteen years old when the Prophet ﷺ passed away. He heard from him, Abu bin Ka'b narrated to me and mentioned something similar.  

سَهْلُ بْنُ سَعْدٍ وَكَانَ قَدْ بَلَغَ خَمْسَ عَشْرَةَ سَنَةً حِينَ تُوُفِّيَ النَّبِيُّ ﷺ وَسَمِعَ مِنْهُ أَخْبَرَنِي أُبَيُّ بْنُ كَعْبٍ وَذَكَرَ نَحْوَهُ  

[Machine] Sahl bin Saad Al-Ansari had seen the Prophet ﷺ , heard from him, and mentioned that he was 15 years old when the Prophet ﷺ passed away. Ubay bin Ka'ab narrated to me that the fatwa they used to issue was considered permissible, and the Prophet ﷺ had permitted it in the early days of Islam. Then, he ordered the ritual cleansing afterwards.  

سَهْلُ بْنُ سَعْدٍ الْأَنْصَارِيُّ وَكَانَ قَدْ رَأَى النَّبِيَّ ﷺ وَسَمِعَ مِنْهُ وَذَكَرَ أَنَّهُ ابْنُ خَمْسَ عَشْرَةَ سَنَةً حِينَ تُوُفِّيَ النَّبِيُّ ﷺ حَدَّثَنِي أُبَيُّ بْنُ كَعْبٍ أَنَّ الْفُتْيَا الَّتِي كَانُوا يُفْتُونَ بِهَا رُخْصَةٌ كَانَ النَّبِيُّ ﷺ رَخَّصَ فِيهَا فِي أَوَّلِ الْإِسْلَامِ ثُمَّ أَمَرَ بِالِاغْتِسَالِ بَعْدُ  

[Machine] "That the Messenger of Allah made it permissible for the believers due to the scarcity of their clothes, but then the Messenger of Allah forbade it later, meaning their saying that water is from water."  

أَنَّ رَسُولَ اللهِ ﷺ جَعَلَهَا رُخْصَةً لِلْمُؤْمِنِينَ لِقِلَّةِ ثِيَابِهِمْ ثُمَّ إِنَّ رَسُولَ اللهِ ﷺ نَهَى عَنْهَا بَعْدُ يَعْنِي قَوْلَهُمْ الْمَاءُ مِنَ الْمَاءِ  

[Machine] The Messenger of Allah ﷺ was asked about the mosque that is founded upon piety. So he said, "It is my mosque."  

أَنَّ رَسُولَ اللهِ ﷺ سُئِلَ عَنِ الْمَسْجِدِ الَّذِيأُسِّسَ عَلَى التَّقْوَى؟ فَقَالَ هُوَ مَسْجِدِي  

[Machine] The Prophet ﷺ said, "The mosque that is established on piety is my mosque."  

أَنَّ النَّبِيَّ ﷺ قَالَ الْمَسْجِدُ الَّذِي أُسِّسَ عَلَى التَّقْوَى مَسْجِدِي هَذَا
