Ammar, the freedman of Banu Hashim, said that some freedmen of Ibn al-Zubayr (may Allah be pleased with them both) had entered ihram when a hyena passed by them. They threw their sticks at it and struck it, and this troubled them. They came to Ibn Umar (may Allah be pleased with them both) and mentioned it to him. Ibn Umar said: "You owe a ram." They said: Is a ram owed by each one of us? He said: "You are being dealt with strictly: each of you owes a ram." Ali (bin Umar) said: The linguists said: "la-mu'azzazun bikum" means "you are being dealt with strictly".
