Hazrat Zuhri (may Allah have mercy on him) says that the noble Companions (may Allah be pleased with them) used to compete in walking and running.

Hazrat Ishaq bin Yazid (may Allah have mercy on him) narrates that I asked Hazrat Saeed al-Musayyib (may Allah be pleased with him) about competing in stone-throwing. He replied, "There is no harm in it."

Hazrat Salim bin Abdullah (may Allah be pleased with him) disliked that anyone should say to another: I will compete with you on the condition that you will make me lie down (i.e., give me a reward, etc.).

Hasan (may Allah have mercy on him) disliked that it be said: "I will compete on the condition that you let me advance."

Ibrahim (may Allah have mercy on him) said that the noble Companions j disliked that a person would say to another: "I will compete with you on the condition that you will let me go ahead, then if I surpass you, the prize will be mine, otherwise it will be yours." He said, this is gambling.

It is narrated from Hazrat Abu Saeed Al-Asam (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) gave a ruling regarding a slave: if he leaves the land of war (Dar al-Harb) before his master, he is free, and if later his owner comes, he will not be returned. But if the owner comes out of Dar al-Harb before the slave, and then the slave comes after him, then the slave will be given to the master.

Hazrat Ibn Abbas (may Allah be pleased with both of them) narrates that the Holy Prophet (peace and blessings be upon him) would set free any slave who became Muslim and arrived from the land of war before his master. On the day of Ta’if, he set free two such slaves.

Hazrat Ikrimah (may Allah be pleased with him) narrates that if a person becomes Muslim in the land of the enemy and comes to the Muslims before his property (slave), and then later his property arrives, then he has a greater right to his property. But if his slave arrives before him, then the slave will be considered free.

Hazrat Mak’hool (may Allah have mercy on him) says that the Muslims did not see any harm in picking up such things from the enemy’s land which had no value there.

Hazrat Qasim and Hazrat Salim (may Allah be pleased with them) say that if you cut down a tree in the enemy's land and make a peg, stick, hammer, board, bowl, or door from it, there is no harm in it. And if there is something there that has value (is used), then give it into the spoils of war.
