Narrated Al-Aswad: `Aisha intended to buy Barira (a slave-girl) in order to manumit her and her masters intended to put the condition that her Al-wala would be for them. `Aisha mentioned that to the Prophet who said to her, "Buy her, as the "Wala" is for the manumitted." Once some meat was presented to the Prophet and `Aisha said to him, "This (meat) was given in charity to Barira." He said, "It is an object of charity for Barira but a gift for us."

Narrated Um 'Atiyya Al-Ansariya: The Prophet went to `Aisha and asked her whether she had something (to eat). She replied that she had nothing except the mutton (piece) which Nusaiba (Um 'Atiyya) had sent to us (Buraira) in charity." The Prophet said, "It has reached its place and now it is not a thing of charity but a gift for us."

Narrated Anas: Some meat was presented to the Prophet (p.b.u.h) and it had been given to Barira (the freed slave-girl of Aisha) in charity. He said, "This meat is a thing of charity for Barira but it is a gift for us."

Narrated Abu Ma`bad: (the slave of Ibn `Abbas) Allah's Apostle said to Mu`adh when he sent him to Yemen, "You will go to the people of the Scripture. So, when you reach there, invite them to testify that none has the right to be worshipped but Allah, and that Muhammad is His Apostle. And if they obey you in that, tell them that Allah has enjoined on them five prayers in each day and night. And if they obey you in that tell them that Allah has made it obligatory on them to pay the Zakat which will be taken from the rich among them and given to the poor among them. If they obey you in that, then avoid taking the best of their possessions, and be afraid of the curse of an oppressed person because there is no screen between his invocation and Allah."

Allah, the Exalted, says (in Surah At-Tawbah): "Take alms from their wealth in order to purify them and sanctify them with it, and pray for them. Verily, your prayer is a source of security for them." Until the end of the verse.

Narrated 'Abdullah bin Abu Aufa: Whenever a person came to the Prophet with his alms, the Prophet would say, "O Allah! Send your Blessings upon so and so." My father went to the Prophet with his alms and the Prophet said, "O Allah! Send your blessings upon the offspring of Abu Aufa."

And Abdullah ibn Abbas (may Allah be pleased with them both) said that ambergris cannot be called rikaz. Ambergris is a thing which the sea throws onto the shore.

And Imam Hasan al-Basri (may Allah have mercy on him) said: One-fifth is obligatory in ambergris and pearls. Although the Prophet (peace and blessings of Allah be upon him) prescribed one-fifth in rikaz (buried treasure). So rikaz is not that which is found in water.

Narrated Abu Huraira The Prophet said, "A man from Bani Israel asked someone from Bani Israel to give him a loan of one thousand Dinars and the later gave it to him. The debtor went on a voyage (when the time for the payment of the debt became due) but he did not find a boat, so he took a piece of wood and bored it and put 1000 diners in it and threw it into the sea. The creditor went out and took the piece of wood to his family to be used as fire-wood." (See Hadith No. 488 B, Vol. 3). And the Prophet narrated the narration (and said), "When he sawed the wood, he found his money."

And Imam Malik (may Allah have mercy on him) and Imam Shafi’i (may Allah have mercy on him) said: Rikaz is the treasure from the time of ignorance (pre-Islamic era). Whether the amount found is little or much, one-fifth is to be taken from it. And a mine is not rikaz. And the Prophet (peace and blessings of Allah be upon him) said regarding mines: If someone falls into it or dies while working in it, then his life is lost in vain. And in rikaz, one-fifth is due. And Caliph Umar bin Abdul Aziz used to take one-fortieth from mines: five out of two hundred coins. And Imam Hasan al-Basri (may Allah have mercy on him) said: Whoever finds rikaz in the land of war, one-fifth is to be taken from it, and if it is found in a land of peace and treaty, then zakat, one-fortieth, is to be taken from it. And if something is found in the land of the enemy, it should be returned (perhaps it is the property of a Muslim); if it is the property of the enemy, then one-fifth is to be paid from it. And some people said: A mine is also rikaz, like the buried treasure of the time of ignorance, because the Arabs say «أركز المعدن» when something comes out of it. Their answer is: If something is gifted to a person, or he earns profit, or his garden yields much fruit, they say «أركزت» (even though these things are, by consensus, not rikaz). Then these people contradicted their own statement. They say: Hiding rikaz is not bad, and one-fifth need not be given.
