وَعَن أبي أَيُّوب وَجَابِر وَأنس: أَن هَذِه الْآيَة نَزَلَتْ (فِيهِ رِجَالٌ يُحِبُّونَ أَنْ يَتَطَهَّرُوا وَاللَّهُ يحب المطهرين) قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «يَا مَعْشَرَ الْأَنْصَارِ إِنَّ اللَّهَ قَدْ أَثْنَى عَلَيْكُمْ فِي الطَّهُورِ فَمَا طَهُورُكُمْ قَالُوا نَتَوَضَّأُ لِلصَّلَاةِ وَنَغْتَسِلُ مِنَ الْجَنَابَةِ وَنَسْتَنْجِي بِالْمَاءِ قَالَ فَهُوَ ذَاك فعليكموه» . رَوَاهُ ابْن مَاجَه

Abū Ayyūb, Jābir, and Anas said that this verse was revealed: ‘In it are men who love to purify themselves, and God loves those who purify themselves.’ The Messenger of God said: ‘People of the Anṣār, God has praised you for purification. What does your purification consist of?’ They replied: ‘We perform ablution for prayer, wash after major ritual impurity, and cleanse ourselves with water.’ He said: ‘That is it; keep doing it.’ Ibn Mājah transmitted it.
