"Abu Ayyub Al-Ansari, Jabir bin 'Abdullah, and Anas bin Malik told me that when this Verse: "In it (the mosque) are men who love to clean and to purify themselves. And Allah loves those who make themselves clean and pure." was revealed, the Messenger of Allah said: 'O Ansar! Allah has praised you for your cleanliness. What is the nature of your cleanliness?' They said: 'We perform ablution for prayer and we take bath to cleanse ourselves of impurity due to sexual activity, and we clean ourselves with water (after urinating). He said: 'This is what it is. So adhere to it.'"  

أَنَّ هَذِهِ الآيَةَ نَزَلَتْ {فِيهِ رِجَالٌ يُحِبُّونَ أَنْ يَتَطَهَّرُوا وَاللَّهُ يُحِبُّ الْمُطَّهِّرِينَ} قَالَ رَسُولُ اللَّهِ ﷺ يَا مَعْشَرَ الأَنْصَارِ إِنَّ اللَّهَ قَدْ أَثْنَى عَلَيْكُمْ فِي الطُّهُورِ فَمَا طُهُورُكُمْ قَالُوا نَتَوَضَّأُ لِلصَّلاَةِ وَنَغْتَسِلُ مِنَ الْجَنَابَةِ وَنَسْتَنْجِي بِالْمَاءِ قَالَ هُوَ ذَلِكَ فَعَلَيْكُمُوهُ

أَنَّ هَذِهِ الْآيَةَ لَمَّا نَزَلَتْ {فِيهِ رِجَالٌ يُحِبُّونَ أَنْ يَتَطَهَّرُوا} [التوبة 108] قَالَ رَسُولُ اللَّهِ ﷺ «يَا مَعْشَرَ الْأَنْصَارِ إِنَّ اللَّهَ قَدْ أَثْنَى عَلَيْكُمْ فِي الطُّهُورِ خَيْرًا فَمَا طُهُورُكُمْ هَذَا؟» قَالُوا نَتَوَضَّأُ لِلصَّلَاةِ وَنَغْتَسِلُ مِنَ الْجَنَابَةِ وَنَسْتَنْجِي بِالْمَاءِ قَالَ هُوَ ذَاكَ فَعَلَيْكُمْ بِهِ  

[Machine] "The Messenger of Allah ﷺ said: 'O Ansar! Allah has praised you for your goodness in purification. So what is your method of purification?' They replied: 'O Messenger of Allah, we perform ablution for prayer and we wash ourselves from impurity.' The Messenger of Allah ﷺ said: 'Is there anything else besides that?' They said: 'No, except that when one of us comes out of the lavatory, he prefers to cleanse himself with water.' The Messenger of Allah ﷺ said: 'That is what you should do.'"  

رَسُولُ اللهِ ﷺ يَا مَعْشَرَ الْأَنْصَارِ إِنَّ اللهَ قَدْ أَثْنَى عَلَيْكُمْ خَيْرًا فِي الطُّهُورِ فَمَا طُهُورُكُمْ هَذَا؟ قَالُوا يَا رَسُولَ اللهِ نَتَوَضَّأُ لِلصَّلَاةِ وَنَغْتَسِلُ مِنَ الْجَنَابَةِ فَقَالَ رَسُولُ اللهِ ﷺ فَهَلْ مَعَ ذَلِكَ غَيْرُهُ قَالُوا لَا غَيْرَ أَنَّ أَحَدَنَا إِذَا خَرَجَ مِنَ الْغَائِطِ أَحَبَّ أَنْ يسْتَنْجِيَ بِالْمَاءِ فَقَالَ رَسُولُ اللهِ ﷺ هُوَ ذَاكَ فَعَلَيْكُمُوهُ
