16. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mansur ibn Yunus from abu Basir who has said the following: “Once Abu ‘Abdillah عليه السلام said, ‘One of you drinks water and for this Allah admits him into paradise.’ The Imam then said, ‘He picks up the bowl of water and places it in his mouth, then mentions the name of Allah and then he drinks. He then removes it from his mouth and expresses praise for Allah, even though he still has a desire to drink. He then drinks and removes the bowl of water from his mouth and expresses praise for Allah. He then drinks and then removes and expresses praise for Allah. Thus, Allah, the Majestic, the Glorious, deems his admission to paradise necessary.’”
