Performing ablution for each prayer and offering all prayers in one ablution
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 ـ صلى الله عليه وسلم ـ يَصْنَعُ هَذَا فَأَنَا أَصْنَعُ كَمَا صَنَعَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ .
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 (ﷺ) doing this, and I am doing as the Messenger of Allah (ﷺ) did.'"
