´It was narrated from 'Amr bin 'Amir that Anas mentioned:` "The Messenger of Allah (ﷺ) was brought a small vessel (of water) and he performed Wudu'." I said: "Did the Messenger of Allah (ﷺ) perform Wudu' for every prayer?" He said: "Yes." He said: "What about you?" He said: "We used to pray all the prayers so long as we did not commit Hadath." He said: "And we used to pray all the prayers with (one) Wudu'."

´It was narrated that Anas bin Malik said:` "When the Mu'adhdhin called the Adhan, some of the Companions of the Prophet (S.A.W) would get up and rush to the pillars (in the Masjid) and pray until the Prophet (S.A.W) came out and they were like that. They would pray before Maghrib and there was nothing between the Adhan and Iqamah."
