It is narrated from Hazrat Sa'd bin 'Ubadah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever has been the leader of ten people will come on the Day of Resurrection with his hands bound, and nothing will release them except his justice. And whoever learned the Noble Qur'an and then forgot it, he will meet Allah as a leper.

It is narrated from Hazrat Saad bin Ubadah (may Allah be pleased with him) that an Ansari man came to him and asked, "Tell us what goodness has been placed in the day of Friday?" The Holy Prophet (peace and blessings be upon him) said, "There are five important things regarding it: On this day, Hazrat Adam was created; on this day, Hazrat Adam (peace be upon him) was sent down from Paradise; on this day, Allah took the soul of Hazrat Adam (peace be upon him); on this day, there is an hour in which whatever a servant asks from Allah, Allah surely grants it, provided he does not ask for something sinful or for breaking ties of kinship; and on this day, the Day of Judgment will be established. There is no close angel, earth, sky, mountain, or stone that does not fear the day of Friday."

It is narrated from Hazrat Saad bin Ubadah (may Allah be pleased with him) that once the Holy Prophet (peace and blessings be upon him) passed by me, so I said, "O Messenger of Allah! Tell me of a charitable deed." The Holy Prophet (peace and blessings be upon him) said, "Give water to drink."

It is narrated from Hazrat Sa'd bin Ubadah (may Allah be pleased with him) that his mother passed away, so he submitted to the Holy Prophet (peace and blessings be upon him), "O Messenger of Allah! My mother has passed away. Can I give charity on her behalf?" The Holy Prophet (peace and blessings be upon him) said, "Yes!" He asked, "Then which charity is the best?" The Holy Prophet (peace and blessings be upon him) said, "Providing water to drink." The narrator says that this is the real reason for the family of Sa'd providing water in Madinah Munawwarah.

Qais bin Sa'd says that he also found in the writings of Hazrat Sa'd bin Ubadah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) gave a verdict by taking an oath along with one witness.

It is narrated from Hazrat Sa’d bin Ubadah (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said to him: Supervise and look after the charity of such-and-such tribe, but do not come on the Day of Resurrection in such a state that you are carrying a young camel on your shoulder and it is crying out. He submitted, "O Messenger of Allah! Then assign this responsibility to someone else." Thus, the Holy Prophet (peace and blessings be upon him) took back this responsibility from him.

It is narrated from Hazrat Sa'd bin 'Ubadah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "This tribe of the Ansar is a trial; love for them is a sign of faith and hatred for them is a sign of hypocrisy."

It is narrated from Hazrat Sa'd bin 'Ubadah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever has been the leader of ten people will come on the Day of Resurrection with his hands bound, and nothing will release them except his justice. And whoever learned the Noble Qur'an and then forgot it, he will meet Allah as a leper.
