Abu Salih says that I heard Abu Sa'id (may Allah be pleased with him) saying that gold should be sold for gold with equal weight. I met Ibn Abbas (may Allah be pleased with them both), so I asked him, "The thing you say, do you find its proof in the Qur'an, or have you heard anything about it from the Prophet (peace and blessings be upon him)?" He replied, "I have not found this in the Book of Allah, nor have I heard it directly from the Prophet (peace and blessings be upon him), but Usamah bin Zaid (may Allah be pleased with him) has informed me that the Prophet (peace and blessings be upon him) said: 'Riba (usury) is related to credit.'"

Aamir bin Sa’d (may Allah have mercy on him) says that a man came to Hazrat Sa’d (may Allah be pleased with him) to ask about the plague, so Hazrat Usamah (may Allah be pleased with him) said,“I will tell you about it. I heard the Prophet Muhammad (peace and blessings be upon him) say: The plague is a punishment which Allah the Exalted sent upon the people before you (the Children of Israel). Sometimes it comes and sometimes it goes. Therefore, if an epidemic spreads in a region, do not go into that region, and if an epidemic spreads in a region where you are already present, do not flee from it.”

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that he asked, "O Messenger of Allah! Where will we camp tomorrow, if Allah wills?" This was on the occasion of the conquest of Makkah. The Noble Prophet (peace and blessings be upon him) said, "Has Aqeel left any house for us?" Then the Noble Prophet (peace and blessings be upon him) said, "No Muslim can be the heir of a disbeliever, and no disbeliever can be the heir of a Muslim."

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that sometimes the Prophet Muhammad (peace and blessings be upon him) would fast so continuously that people would say, "Now the Prophet (peace and blessings be upon him) will not leave fasting," and sometimes he would leave fasting so continuously that it would seem as if he would never fast again. However, there were two days in the week that if the Prophet (peace and blessings be upon him) was fasting on them, it was very good, otherwise he would make sure to fast on them, and in no month did he observe as many voluntary fasts as he did in the month of Sha'ban. Seeing this, one day I said, "O Messenger of Allah! Sometimes you fast so much that you are not seen breaking the fast, and sometimes you leave fasting so much that you are not seen fasting. However, there are two days that if they come in your routine of fasting, it is better, otherwise you definitely fast on them." The Prophet (peace and blessings be upon him) asked, "Which two days?" I replied, "Monday and Thursday." The Prophet (peace and blessings be upon him) said, "On these two days, all deeds are presented before the Lord of the worlds, and I wish that when my deeds are presented, I am fasting." Then I said, "I do not see you observing voluntary fasts in any other month as much as I see you fasting in the month of Sha'ban." The Prophet (peace and blessings be upon him) said, "People are heedless of the importance of this month between Rajab and Ramadan, even though in this month deeds are presented before the Lord of the worlds, so I wish that when my deeds are presented, I am fasting."

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that when the Holy Prophet (peace and blessings be upon him) entered the House of Allah, he supplicated in all its corners but did not perform prayer there. Rather, he came outside, faced towards the Ka'bah, and performed two rak'ahs, and said: "This is the Qiblah."

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that when the illness of the Prophet Muhammad (peace and blessings be upon him) became severe during his final sickness, I and some people with me came to Madinah Munawwarah. I presented myself in the service of the Prophet Muhammad (peace and blessings be upon him), and he was silent and not speaking to anyone. When he saw me, the Prophet Muhammad (peace and blessings be upon him) raised his hands towards the sky and then passed them over me. I understood that the Prophet Muhammad (peace and blessings be upon him) was praying for me.

It is narrated from Hazrat Usama (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) departed from Arafat, and Hazrat Usama (may Allah be pleased with him) was riding behind the Noble Prophet (peace and blessings be upon him). The Noble Prophet (peace and blessings be upon him) began to pull the reins of his mount until its ears came close to the front part of the saddle, and the Noble Prophet (peace and blessings be upon him) kept saying: "O people! Adhere to calmness and dignity upon yourselves. There is no virtue in making the camels run fast."

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: There is no usury in a cash transaction; it is only in a deferred transaction.

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that once I went with the Holy Prophet (peace and blessings be upon him) to visit (the chief of the hypocrites) Abdullah bin Ubayy. The Holy Prophet (peace and blessings be upon him) said to him, "I used to forbid you from loving the Jews." He replied, "As'ad bin Zurarah (may Allah be pleased with him) has already turned away from them (that is sufficient)." After saying this, he died after some time.

It is narrated from Hazrat Usama (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) performed prayer inside the House of Allah (the Ka'bah).
