Calculation of Zakāt
Zakāt ( "zakāt", "that which purifies", also Zakat al-mal , "zakat on wealth") is a form of alms-giving treated as a religious tax and/or religious obligation in Islam for all Muslims who meet the necessary criteria of wealth, and one of the Five Pillars of Islam. Beneficiaries of zakat include orphans, widowed, poor muslims, debt-ridden, travelers, zakat collectors, new converts to Islam, Islamic clergy. Zakat is prescribed to cleanse the individual's wealth, heart, and baser characteristics in general, and to replace them with virtues. Zakat is based on income and the type and value of  one's assets/possessions above a minimum amount known as "nisab". The Quran does not provide specific guidelines on which types of wealth are taxable under the "zakat", nor how much is to be donated, and Islamic scholars differ on how much nisab is and other aspects of zakat. However, the amount of zakat paid on capital assets (e.g. money) and stock-in-trade and jewelry is customarily 2.5% (1/40). Zakat is also payable on agricultural goods, precious metals, minerals, and livestock at a rate varying between 2.5 and 20 percent, depending on the type of goods. Income from business , salaries and other means are traditionally exempt. Doctrine. While the Quran talks about the importance of zakat () and gives general guidance on who should receive it (), it does not specify which types of wealth are "zakatable", nor how much is to be given in zakat. While some kinds of wealth are mentioned in the "hadith" in regards to zakat (for example wheat, rye, date, raisin, camels, silver), many others are not. Consequently, the eminent scholar of "fiqh" Yusuf al-Qaradawi emphasizes the importance in zakat regulation of the use of "ijma'" (the agreement of scholars), and "qiyas" (analogy or applying  to a case the same ruling given to a similar case because of common reason ("`illah")). An example of use of "ijma" is the rule that zakah is "obligatory on golden assets at the same rate as it is on silver", (i.e. one fourth of a tenth) despite the fact that only silver had zakat ordered upon it by a hadith by Prophet Muhammad. Zakat regulations on silver and gold are also an example of "qiyas" as both metals are being "used in several countries as measures and store of value", and so are analogous. According to Mohammad Najatuallah  Siddiqui, the ulema (Islamic scholars) are "unanimous in regarding the rates of Zakat as permanently fixed by Islamic law", but "a number" of recent writers, "mostly economists, argue in favour of making these rates amendable to modification". Gold and silver. Al-Qaradawi quotes Imam Al-Shafi‘i in his "Al Risalah" about zakah on gold: "The Prophet of God ordered zakah on silver currency and Muslims after him collected zakah on gold. They were either depending on a hadith of the Prophet that never reached our times or applying analogy because of the similarities between gold and silver as money, since  both were used in several countries as measures and store of value." Jewellery and precious metals — such as gold and silver — come under zakat even if they are used merely for decorative purposes. Zakat can be calculated on property, gold, income, diamond, etc. and before paying zakat, It is important to see who are eligible for zakat. Farm produce. According to al-Qardawi, the grains and fruits mentioned in the hadith on zakah are limited to wheat, rye, date and raisins. However, the majority of scholars prescribed zakah on different kinds of grains and fruits by analogy to those grains  and fruits mentioned by the Prophet, (p) instead of restricting zakah to the items stated in the hadith. ... By the same token, we apply the analogy to silk, milk and other animal products because they are similar to honey, which is mentioned in the Traditions. ... It is reported that 'Umar used analogy with respect to zakah when he ordered zakah on horses after he realized that they had become high in value, saying, "Should we only take one sheep out of every forty sheep and leave horses with nothing?" 'Umar was followed in that respect by Abu Hanifah13. The classic  fiqh nisab for dates or grain is five "wasq" (609.84 kg), so that no zakat is due if the amount of dates or grain possessed is less than that. Zakah is payable on the gross yield of land for each crop. Livestock. "Zakāt" on Livestock or cattle, "Al-An'am" According to "Fiqh az-Zakat" by al-Qaradawi and other traditional handbooks of zakat fiqh (such as one issued by IslamKotob,) zakat on livestock such as sheep, cows and camels should be paid in-kind according to a detailed schedule. Scripture and livestock. Livestock ("Al-An'am") and how God created them  are mentioned in the Quran in Surat Al-An'am (136), and Surat An-Nahl (5). Flocks and feeding the poor are mentioned in Surat Al-Hajj (28). How sinners will be punished in Hell for not having paid due zakat on livestock is mentioned in the hadith: Narrated Abu Dhar: Once I went to him (the Prophet ) and he said, "By Allah in Whose Hands my life is (or probably said, 'By Allah, except Whom none has the right to be worshipped), whoever has camels or cows or sheep and does not pay their zakat, those animals will be brought  on the Day of Resurrection far bigger and fatter than before and they will tread him under their hooves, and will butt him with their horns, and (those animals will come in circle): When the last does its turn, the first will start again, and this punishment will go on till Allah has finished the judgments amongst the people." (Bukhari, Vol.2, Book 24, No. 539) Camels. The following table shows the ranges of camel numbers and the corresponding due zakah. Cows, and buffaloes (Domestic and not wild). According to al-Qaradawi there are no hadiths / ahadith that prescribe the nisab  for cows: There are no sahih (authentic / sound) hadiths that provide us with the nisab and rates of zakah on cows as we have seen in the case of camels. This may be because cows were rare in the area of Hijaz (around Makkah and Madinah); it may be also because cows are close in size and value to camels, so the Prophet did not determine their rates on the assumption of their obvious similarity. But the fact that there is no sahih hadith on the issue has left the jurists with varying views on the determination of nisab and  rates. However, the "reputed position upheld by the four schools of jurisprudence" is that the nisab is 30 cows, and so, the due zakah on 30-39 cows is a one-year old cow, and on 40-59 cows is a two-year-old cow, and so on (see below). Sheep and goats. There is no zakat on sheep and goats until their number reaches forty. [Neither male or female is specified]. Contemporary practice. As of 2010, Zakat was mandatory by state law and collected by the state in six Muslim majority countries: Libya, Malaysia, Pakistan, Saudi Arabia, Sudan, and  Yemen, according to researcher Russell Powell. There were government-run but voluntary Zakat contribution programs in Bahrain, Bangladesh, Egypt, Indonesia, Iran, Jordan, Kuwait, Lebanon, and the United Arab Emirates. The states where zakat is compulsory differ in their definition of what assets (and sometimes income) are "zakatable"—eligible for contributing zakat. A 1995 study by Fouad Abdullah al-Omar found many differences.
