He also reported God's messenger as saying, “The key of prayer is purification, saying ‘God is most great’ makes it a sacred state, and the salutation brings the sacred state to an end.”
Abu Dawud, Tirmidhi and Darimi transmitted it, and Ibn Majah transmitted it both from 'Ali and from Abu Sa'id.
Suwaid b. an-Nu‘man said that he went out with God’s messenger in the year of Khaibar , and when they were at as-Sahba’ which is very near Khaibar, he prayed the afternoon prayer. He then called for food, and when only some flour was produced, he ordered it to be moistened;
then God’s messenger and the company ate. After that he got up to pray the sunset prayer, and when he and the company had rinsed their mouths he prayed without performing ablution.
