عبد الله بن عمر

"We were in Mecca, and the prices of sacrificial animals increased. We bought for one dinar, then for two dinars, and then it reached seven dinars, and after that, we could not find any—neither for a little nor a lot. Hisham al-Mukari wrote to Abu al-Hasan (as) about this, and Imam (as) replied: 'Consider the first price, the second, and the third, add them together, and then give in charity an amount equivalent to one-third of it.'"

“Once we were in Makkah and animal for offering became very expensive. We bought for one dinar then, two dinar and then we could not find anything for less or more. Hisham al-Mukariy then wrote a note to abu al-Hassan (a.s.), and informed him (the Imam) of what we had bought and then could not find anything for less or more. He (the Imam) then wrote, ‘Consider the first, second and third prices, then give in charity one-third of the average of such prices.’”
