It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: "If the seller and the buyer have a dispute and neither of them has a witness, then the statement of the seller will be accepted; otherwise, both should return their respective items."

It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: "If the seller and the buyer disagree and the goods are still present as they were, then the statement of the seller will be accepted; otherwise, both should take back their respective things."

Qasim says that once there was a dispute over the price of something between Sayyiduna Ibn Mas'ud and Sayyiduna Ash'ath (may Allah be pleased with them both). One person was saying ten and the other twenty. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: Appoint someone as an arbitrator between you and me. He said: I appoint you as the arbitrator. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: Then I will give the same decision as the Prophet (peace and blessings of Allah be upon him) gave, that "If there is a dispute between the seller and the buyer (the one who buys and the one who sells), and neither has any witnesses, then the statement of the seller will be accepted, or both should conduct a new transaction."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) at the time of the Battle of Khaybar allotted two shares for the horse and one share for the rider. According to another narrator, the wording is that for a man and his horse, three shares were allotted, of which one share was for the man and two shares were for the horse.

Ziyad bin Jubair says that I saw a man come to Sayyiduna Ibn Umar (may Allah be pleased with them both) and ask this question: "I have made a vow that I will fast every Wednesday. Now, if Eid al-Adha or Eid al-Fitr falls on a Wednesday, what should I do?" Sayyiduna Ibn Umar (may Allah be pleased with them both) replied: "Allah has commanded the fulfillment of vows, and the Prophet (peace and blessings be upon him) has forbidden us from fasting on the Day of Sacrifice (the tenth of Dhul-Hijjah)."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) said: "When you are three people, then two of you should not whisper to each other leaving the third one out."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever frees his share of a slave, he will be obliged to free the slave completely according to the price set by just men."

Saeed bin Jubair (may Allah have mercy on him) says that at the time of departure from Arafat towards Muzdalifah, we were with Sayyiduna Ibn Umar (may Allah be pleased with them both). He led us in the complete Maghrib prayer, then said «الصلوة» and led us in two rak'ahs (of Isha), and said that the Prophet (peace and blessings of Allah be upon him) also did at this place just as I have done.

Once, Sayyiduna Ibn Umar (may Allah be pleased with them both) passed by Sayyiduna Abu Hurairah (may Allah be pleased with him), who at that time was narrating this hadith of the Prophet (peace and blessings be upon him): The Messenger of Allah (peace and blessings be upon him) said, "Whoever goes with a funeral and offers the funeral prayer will receive a reward equal to one qirat, and if he also remains present at the time of burial, he will receive a reward equal to two qirats, each of which is greater than Mount Uhud." Upon hearing this, Sayyiduna Ibn Umar (may Allah be pleased with them both) said, "Abu Hurairah! Consider carefully what you are narrating from the Prophet (peace and blessings be upon him)." At this, Sayyiduna Abu Hurairah (may Allah be pleased with him) stood up and took him to Sayyidah Aisha (may Allah be pleased with her) and said to her, "O Mother of the Believers! I ask you by Allah, did you hear the Prophet (peace and blessings be upon him) say that whoever goes with a funeral and offers the funeral prayer will receive a reward equal to one qirat, and if he also remains present at the time of burial, he will receive a reward equal to two qirats?" She replied, "By Allah! Yes." After this, Sayyiduna Abu Hurairah (may Allah be pleased with him) said, "Planting date palms or engaging in business in the markets was not the reason I did not attend the service of the Prophet (peace and blessings be upon him) (because I did not do these things). I used to seek two things from the Prophet (peace and blessings be upon him): one was the knowledge that he taught me, and the other was the morsel that he fed me." Sayyiduna Ibn Umar (may Allah be pleased with them both) said, "Abu Hurairah, you used to stay with the Prophet (peace and blessings be upon him) more than us, and you are more knowledgeable than us regarding his hadith."

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger (peace and blessings of Allah be upon him) said: "If a pilgrim in the state of Ihram does not find shoes, he should wear socks, but he should cut them below the ankles."
