It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that once the Holy Prophet (peace and blessings of Allah be upon him) climbed a hillock in Madinah Munawwarah and said, "Do you see what I am seeing?" The people replied, "No." The Holy Prophet (peace and blessings of Allah be upon him) said, "I am seeing that tribulations are appearing in your homes like the falling of raindrops."

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. Hazrat Usama (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 (may Allah be pleased with him) that on the day of Arafah, the Noble Prophet (peace and blessings be upon him) seated him behind himself on his mount. People began to say, "Our companion will inform us of what the Noble Prophet (peace and blessings be upon him) did." Hazrat Usama (may Allah be pleased with him) reported that when the Noble Prophet (peace and blessings be upon him) departed after standing at Arafat, he pulled the head of his mount so much that it touched, or nearly touched, the middle part of the saddle, and the Noble Prophet (peace and blessings be upon him) began to gesture to the people to remain calm, until they reached Muzdalifah. Then Hazrat Fadl bin Abbas (may Allah be pleased with him) was made to sit behind him. People began to say, "Our companion will inform us of what the Noble Prophet (peace and blessings be upon him) did." Accordingly, he reported that the Noble Prophet (peace and blessings be upon him) continued to move slowly as he had the previous day, except that when he reached the valley of Muhassir, he quickened his pace until he had passed through it.

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah 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 the Noble Prophet (peace and blessings be upon him) departed from Arafat and reached the valley where people used to make their mounts sit down. The Noble Prophet also made his she-camel sit there, then he urinated and cleansed himself with water, then performed ablution with water, but not excessively. I said, "O Messenger of Allah! The time for prayer has come." The Noble Prophet (peace and blessings be upon him) replied, "The prayer is ahead of you." Then he mounted his ride and reached Muzdalifah, where he performed the Maghrib prayer. Then people made their mounts sit at their respective places, and before they could unload their belongings, the Isha prayer was established. He performed the prayer, and no prayer was performed between the two.

It is narrated from Hazrat Usama bin Zaid (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: "Riba (usury/interest) is related to credit (deferred payment)."

It is narrated from a freed slave of Hazrat Usama bin Zaid (may Allah be pleased with him) that one day he was with Hazrat Usama (may Allah be pleased with him) in Wadi Qura in search of his wealth. It was the habit of Hazrat Usama (may Allah be pleased with him) that he used to fast on Mondays and Thursdays. His slave asked him, "Despite being so old and weak, why do you observe the fast of Monday and Thursday so regularly?" He replied, "The Holy Prophet (peace and blessings be upon him) also used to fast on Mondays and Thursdays. Someone asked him the reason for this, so the Holy Prophet (peace and blessings be upon him) said, 'On Mondays and Thursdays, the deeds of people are presented.'"

Dhakwan says that once Abu Sa'id Khudri (may Allah be pleased with him) sent me to Ibn Abbas (may Allah be pleased with both of them) to ask: Regarding what you say about the transaction of sarf (exchange of gold and silver), do you find its evidence in the Qur'an or have you heard anything about it from the Prophet (peace and blessings of Allah be upon him)? He replied: I have not found this matter in the Book of Allah, nor have I heard it directly from the Prophet (peace and blessings of Allah be upon him), but Usama bin Zaid (may Allah be pleased with him) informed me that the Prophet (peace and blessings of Allah 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. Hazrat Usama (may Allah be pleased with him) said,“I will tell you about it. I heard the Noble Prophet (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 to that region, and if an epidemic spreads in a region where you are already present, do not flee from it.”

Abu Wa'il says that someone said to Hazrat Usama (may Allah be pleased with him), "Why do you not speak to Hazrat Uthman (may Allah be pleased with him)?" He replied, "Do you think that whatever I say to him, I will also tell you? Whatever I say to him is between me and him. I do not like to be the first to disclose this matter. And by Allah! I cannot say about any man that you are the best of all people, even if he is my ruler, while I have also heard the Prophet Muhammad (peace and blessings be upon him) say regarding this that on the Day of Resurrection a man will be brought and thrown into Hell, and his intestines will come out, and he will go around with them as a donkey goes around a millstone. Seeing this, all the people of Hell will gather around him and say, 'O so-and-so! What has happened to you? Did you not command us to do good and forbid us from evil?' He will reply, 'I used to command you to do good, but I did not do it myself, and I used to forbid you from sins, but I used to do them myself.'"
