It is narrated from Sayyiduna Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "For any one of you to have his stomach filled with vomit is better than to have it filled with poetry."

Mus'ab bin Sa'd says that once I prayed with my father, and in bowing (ruku'), I joined my hands and placed them between my knees. He struck my hands and said that in the beginning we used to do like this, but later we were commanded to place our hands on our knees.

It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“Whoever eats seven Ajwa dates in the morning on an empty stomach, no poison or magic will harm him that day.”

The previous hadith is also narrated through this second chain of transmission.

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“I declare the area between the two boundaries of Madinah as a sanctuary (Haram), therefore no tree should be cut here, nor should any animal be hunted here.”And he said,“Madinah is the best place for people, if only they had certainty about it. If anyone leaves here out of dislike, Allah Almighty will settle someone better than him in his place. And whoever remains steadfast in facing the hardships and difficulties of this place, I will intercede for him on the Day of Resurrection.”

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that once the Prophet (peace and blessings of Allah be upon him) was coming from ‘Aliyah. On the way, he passed by the mosque of Banu Mu’awiyah. The Prophet (peace and blessings of Allah be upon him) entered this mosque and offered two rak’ahs of prayer. We also performed this prayer with the Prophet (peace and blessings of Allah be upon him). After that, the Prophet (peace and blessings of Allah be upon him) made a long supplication, and after finishing, he said:“I asked my Lord for three things, of which He granted me two and did not grant one. One request I made was that my Ummah should not be destroyed by drowning in the sea; Allah granted me this request. The second request I made was that my Ummah should not be destroyed by famine; Allah granted me this request as well. And the third request I made was that my Ummah should not fight among themselves, but Allah refused to grant this supplication.”

It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“I am amazed at the decree and decision of Allah regarding the believing servant: if any good comes to him, he gives thanks to his Lord, and if any calamity befalls him, he is patient over it with the intention of reward (both patience and gratitude are beloved to Allah). The believer is rewarded for everything, even for the morsel that he lifts and places in his wife’s mouth.”

Mus'ab bin Sa'd says that once I prayed with my father, and in bowing (ruku'), I clasped my hands together and placed them between my knees. He forbade me from this and said that in the beginning we used to do this, but later we were prohibited from it.

It is narrated from Sayyiduna Sa’d bin Abi Waqqas, Sayyiduna Khuzaymah bin Thabit, and Sayyiduna Usamah bin Zaid (may Allah be pleased with them) that once the Prophet (peace and blessings be upon him) said:“This plague is a punishment that came upon the nations before you. Therefore, if an area is afflicted with this epidemic, do not go there, and if you are in an area where this epidemic spreads, do not leave from there.”

It is narrated from Sayyiduna Sa'd (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I will describe to you a characteristic of the Dajjal which no prophet before me has described. Remember! The Dajjal will be one-eyed (and will claim lordship), whereas Allah is not one-eyed."
