It is narrated from Sayyiduna Sa'id bin Zaid (may Allah be pleased with him) that once—when the Prophet (peace and blessings be upon him) was in Makkah and with him was Sayyiduna Zaid bin Harithah (may Allah be pleased with him)—Zaid bin Amr bin Nufail passed by both of them. They invited Zaid to eat, as they were sitting at the dining spread at that time. Zaid said, "Nephew! I do not eat the meat of animals that are slaughtered in front of idols." (This incident is from before Prophethood.) After that, the Prophet (peace and blessings be upon him) was never seen eating such food. Sayyiduna Sa'id (may Allah be pleased with him) says: One day I submitted in the court of the Messenger (peace and blessings be upon him): "O Messenger of Allah! You yourself have seen my father and you also know about him. If he had found your time of Prophethood, he would surely have believed in you and followed you. Please seek forgiveness for him." The Prophet (peace and blessings be upon him) said: "Yes! I will seek forgiveness for him, because on the Day of Resurrection he will be raised alone equal to a whole nation."

Abu Salamah says that once Marwan said, "Go and reconcile between the two of them, that is, Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) and the narrator." We reached Sayyiduna Sa'id (may Allah be pleased with him), and he said, "Do you think that I have usurped any right of that woman? I am an eyewitness to this matter. I heard the Prophet (peace and blessings of Allah be upon him) say: 'Whoever unjustly seizes even a handspan of land, a collar of that land, taken from all seven earths, will be placed around his neck. And whoever establishes an alliance with a people without their permission, upon him is the curse of Allah. And whoever, by swearing an oath, unlawfully acquires the wealth of a Muslim, Allah will never bless it for him.'"

Amr bin Harith says that once, on the occasion of my visit to Madinah Munawwarah, I had my brother divide the share for me. Upon this, Sayyiduna Saeed bin Zaid (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "There is no blessing in the price of land or a house unless it is invested back into land or a house."

Abdullah bin Abdur Rahman says that I have come to know this saying of Hazrat Luqman (peace be upon him) that he said to his son: "Son! Do not acquire knowledge so that you may boast over the scholars through it, or argue with the ignorant and foolish, or make yourself prominent in gatherings." Then he narrated this hadith of Sayyiduna Saeed bin Zaid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "The greatest usury is to unjustly violate the honor of a Muslim. The womb (kinship) is a branch of the Most Merciful. Whoever severs kinship, Allah will make Paradise forbidden for him."

It is narrated from Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Whoever is killed while protecting his wealth is a martyr, whoever is killed while protecting his family is also a martyr, whoever is killed while protecting his religion is also a martyr, and whoever is killed while protecting his life is also a martyr."

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

It is narrated from Sayyiduna Saeed bin Zaid (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "O group of Arabs! Give thanks to Allah that He has removed taxes from you."

It is narrated from Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I participated with my uncles—while I was still young—in the Hilf al-Mutayyibeen, which is also called Hilf al-Fudul. I would not like to break this agreement even if I were given red camels in exchange for it."

Imam Zuhri (may Allah have mercy on him) narrates that the Prophet (peace and blessings be upon him) also said: "Every treaty that Islam has made, its severity has only increased, and Islam does not advocate this." However, the Prophet (peace and blessings be upon him) established brotherhood between the Quraysh and the Ansar.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once Sayyiduna Umar Farooq (may Allah be pleased with him) asked him, "O boy! Have you heard this issue from the Prophet (peace and blessings of Allah be upon him) or from any companion, that if a person has doubt in his prayer, what should he do?" While this conversation was taking place, Sayyiduna Abdur Rahman bin Awf (may Allah be pleased with him) was seen coming from the front. He asked, "What are you discussing?" Sayyiduna Umar (may Allah be pleased with him) said, "I was asking this boy whether he has heard this issue from the Prophet (peace and blessings of Allah be upon him) or from any companion, that if a person has doubt in his prayer, what should he do?" Sayyiduna Abdur Rahman (may Allah be pleased with him) said, "I heard the Prophet (peace and blessings of Allah be upon him) say: 'If any of you has doubt in his prayer and does not remember whether he has prayed one rak'ah or two, then he should count it as one rak'ah. If he doubts between two and three, he should consider them as two. If he doubts between three and four, he should count them as three. After that, upon completing the prayer, before saying salam, he should perform two prostrations of forgetfulness (sujood as-sahw).'"
