عَنْ عَمْرِو بْنِ عَامِرٍ قَالَ: سَمِعْتُ أَنَسًا يَقُولُ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَتَوَضَّأُ عِنْدَ كُلِّ صَلَاةٍ، قَالَ: قُلْتُ: وَأَنْتُمْ كَيْفَ كُنْتُمْ تَصْنَعُونَ؟ قَالَ: كُنَّا نُصَلِّي الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ مَا لَمْ نُحْدِثْ
It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him and his family) used to perform ablution for every prayer. I (Amr bin Aamir) asked: And how did you companions do? He said: As long as we did not lose our ablution, we would continue to perform prayers with the same ablution.
