وَعَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا
قَالَتْ: «بَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَامَ عُمَرُ خَلْفَهُ بِكُوزٍ مِنْ مَاءٍ فَقَالَ: مَا هَذَا يَا عمر؟ قَالَ: مَاءٌ تَتَوَضَّأُ بِهِ. قَالَ: مَا أُمِرْتُ كُلَّمَا بُلْتُ أَنْ أَتَوَضَّأَ وَلَوْ فَعَلْتُ لَكَانَتْ سُنَّةً
Aishah told of God’s messenger passing water and Umar standing behind him with a jug of water. He said, “What is this, Umar?” He replied, “Water for you to perform ablution with.” He said, “I have not been commanded to perform ablution every time I pass water. If I were to do so it would become a sunna”
