Sayyiduna Abdullah bin Buraidah Aslami رضي الله عنه reports that Ubaidullah bin Ziyad began to have doubts about the Hawd (the Prophet’s Pond), so he summoned Sayyiduna Abu Barzah Aslami رضي الله عنه. When he went to him, his companions said to him: The Amir has called you so that we may ask you about the Hawd—did you hear anything from the Messenger of Allah صلى الله عليه وآله وسلم regarding the Hawd? He said: Yes, I heard the Messenger of Allah صلى الله عليه وآله وسلم mention it, and whoever denies it, Allah Almighty will not let him drink from it.
