It is narrated from Ikrimah that Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) used to perform all five prayers with one ablution, but Sayyiduna Ali (may Allah be pleased with him) would perform ablution for every prayer, and he recited this verse: «إِذَا قُمْتُمْ إِلَى الصَّلَاةِ فَاغْسِلُوا وُجُوهَكُمْ وَأَيْدِيَكُمْ» [5-المائدة:6] "When you stand for prayer, wash your faces and hands."
