Abu al-Tayyah reported on the authority of a shaykh (an old man):
When Abdullah ibn Abbas came to Basrah, people narrated to him traditions from AbuMusa.Therefore Ibn Abbas wrote to him asking him about certain things.In reply AbuMusa wrote to him saying: One day I was in the company of the Messenger of Allah (ﷺ).He wanted to urinate.Then he came to a soft ground at the foot of a wall and urinated.He (the Prophet) then said: If any of you wants to urinate, he should look for a place (like this) for his urination.
