Abdullah bin Abbas reported,

We were with the Prophet ﷺ when he went to relieve himself. Afterwards he came out and called for food. On one occasion, he said, food was brought to him.Someone asked, "Messenger of Allah, will you not perform ablution?"He replied, "I am not about to pray, so why should I perform ablution?"
