Fadl bin Mubashshir said:
"I saw Jabir bin 'Abdullah performing every prayer with one ablution, and I said: 'What is this?' He said: 'I saw the Messenger of Allah doing this, and I am doing as the Messenger of Allah did.'"

حَدَّثَنَا إِسْمَاعِيلُ بْنُ تَوْبَةَ، حَدَّثَنَا زِيَادُ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا الْفَضْلُ بْنُ مُبَشِّرٍ، قَالَ رَأَيْتُ جَابِرَ بْنَ عَبْدِ اللَّهِ يُصَلِّي الصَّلَوَاتِ بِوُضُوءٍ وَاحِدٍ . فَقُلْتُ مَا هَذَا فَقَالَ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَصْنَعُ هَذَا فَأَنَا أَصْنَعُ كَمَا صَنَعَ رَسُولُ اللَّهِ ﷺ .
