Abu Abdullah Jafar ibn Mohammad ibn Hakim ibn Abdurrahman ibn Adam Rudaki Samarghandi (859 - c. 941) () or Rudaki was a Persian poet. He was born in Panjakent, Tajikistan and lived in Samarghand. Rudaki translated the old Indian fable book Panchatantra into Persian verse. His poems are collected in diwan.

Baba Taher
Baba Taher () was a Persian poet. He lived in Hamadan, a city in Iran. Baha Taher songs are read in Pahlavi languages. His tomb is in Hamadan, western Iran.
Amir Khosrow
Hakīm Abul-Hasan Yamīn al-Dīn Khusrow Balkhi Dehlavi (1253-1325) () or Amir Khosrow is a Persian poet. Amir Khusrow lived in Delhi. His poems are in Persian and Hindi.
Allaudin Khilji (1296 A.D - 1316 A.D) had a court minister named Hazrat Amir Khusro who was said to be highly gifted in music with an exceptionally innovative mind. His contribution to Hindustani classical music was said to be unmatched. It is also said that he created the Sitar (probably inspired by the Veena and other string instruments of Persia). The modification of the Pakhawaj into the Tabla is also credited to him.
It has also been said that Amir Khusro introduced many styles of singing including Khayal, Tarana, Ghazal and Qawali. He is credited for some most popular Ragas like Yaman, Poorya and Poorvi.
Hafez
Khwajeh Shams al-Din Muhammad Hafez-e Shirazi (also spelled Hafiz) (born between 1310 and 1337, believed to have died at age 69) () or Hafez is a Persian poet. Hafez was born in Shiraz, Iran. Hafez learnt the Quran by heart at an early age. His poems are collected in Divan e Hafez. William Jones translated his work into English in 1771.
Despite his profound effect on Persian life and culture and his enduring popularity and influence, few details of his life are known, and particularly about his early life there is a great deal of more or less mythical anecdote. Some of the early tazkeras (biographical sketches) mentioning Hafez are generally considered unreliable. One early document discussing Hafez' life is the preface of his Divān, which was written by an unknown contemporary of Hafez whose name may have been Moḥammad Golandām. The generally accepted modern edition of Hafez's Divān is known as "Qazvini-Ḡani", edited by Moḥammad Qazvini and Qāsem Ḡani.
Many semi-miraculous mythical tales were woven around Hāfez after his death. Four of them are:
Forough Farrokhzad
Forough Farrokhzad (January 5, 1935 — February 13, 1967) () was an Iranian poetess. She lived in Tehran. In 1967, she died in a car accident. She was thirty-two. Maryam Dilmaghani translated her poems to English in 2006.
Ahmad Shamlou
Ahmad Shamlou (December 12, 1925 – July 24, 2000) () or Shamlou was a Persian poet, writer and journalist. In 1954, he was arrested. He was freed in 1955. Shamlou published more than seventy books. He wrote short stories, novels, plays, essays and poems. He died in Tehran and was buried in Karaj.
Parvin E'tesami
Parvin E'tesami (March 17, 1907 - April 5, 1941; ) is an Iranian poetess. She was daughter of Yosuf E'tesami, Iranian poet and writer. She started poetry when she was 9. Alladin Pazargadi translated her works from Persian into English in 2000.
Hafiz
Hafiz or Hafez may mean:
Jihad
Jihad is an Arabic word meaning "to struggle". Muslims (believers in Islam) use this word to talk about defending the faith and protecting their family and nation, as well as defending innocent people. It can also mean fighting with yourself to become a better person. It is an official part of Shi'a Islam, but it is not an official part of Sunni Islam, though some call it the sixth pillar of Islam. In some cases, there have been 'Jihads' that have self immolated themselves, in order to get into heaven. There are suicide bombers, who blow themselves up, because they think that it is right and that they are cleaning the world's filth. This is, however, wrong in Islam. It is a major sin to commit suicide or homicide. Killing another human being in Islam is the equivalent of killing all of humanity. On the contrary, saving another human being's life is the equivalent of saving all of humanity.
Postfix notation
Postfix notation is a mathematical notation. It is a way to write down equations and other mathematical formulae. Postfix notation is also known as Reverse Polish Notation. The notation was invented by Charles Hamblin in 1920. He wanted to simplify writing logic equations. He used Jan Łukasiewicz's prefix notation.
When postfix notation is used, no grouping elements (like parenthesis) are needed.
Some computer languages, like Postscript use Postfix notation. It is also used in some models of Hewlett-Packard calculators
With postfix notation, the operations are noted after their arguments. Because of this, postfix is relatively easy to do with computers that have a stack to do calculations.
Reverse Polish Notation uses a system that involve "stacks", each of which stores a certain value in specific ranks. The stacks usually start off with the first stack (often called the X stack), followed by the second stack (often called the Y stack), the third stack, and so on. New values can be entered on the first stack by pushing up the stack ranks by one. On a Reverse Polish Notation calculator, the "Enter" function would do the same.
Using a common operator (plus, minus, multiply, or divide) will make the operator act from the first stack to the second stack. For example, the Reverse Polish Notation "12 3 /" means "take the numbers 12 and 3, then divide 12 by 3". On a Reverse Polish Calculator, this is written as "12 Enter 3 /", to denote each declared ranking up of the stacks.
Reverse Polish Notation is able to deal with expressions involving brackets too. Suppose there is a normal equation "4 * (5 + 8)". In Reverse Polish Notation, this expression will be formatted as "5 8 + 4 *". The "5 8 +" part refers to the bracket "5 + 8" to equal 13. The "4 *" part refers to multiplying the result together to get 52. On that step, the resulting stack from adding 5 and 8 is automatically raised one rank after adding in the new value 4. Then using the multiply operator will multiply the sum of 5 and 8 by 4 will equal 52.
Documentation included with early Hewlett-Packard calculators explained RPN as the same method you would use to evaluate an expression using paper and pencil. Basically, first you write down the arguments and then perform the arithmetic function. From the calculator's perspective, you must provide the argument(s) before calling the function. The benefit of a calculator with RPN is that you are always certain to which numbers (or intermediate calculation results) a function is being applied.
Infix notation
Infix notation is the common arithmetic and logical formula notation, in which operators are written infix-style between the operands they act on (e.g. 2 + 2). It is not as simple to parse by computer as prefix notation ( e.g. + 2 2 ) or postfix notation ( e.g. 2 2 + ), but many programming languages use it due to its familiarity.
In infix notation, unlike in prefix or postfix notations, parentheses surrounding groups of operands and operators are necessary to indicate the intended order in which operations are to be performed. In the absence of parentheses, certain precedence rules determine the order of operations. These are explained in the order of operations article.
Fiqh
Fiqh or Islamic jurisprudence () is an expansion of Sharia law and is meant to be used with fatwas by Islamic clerics (known as 'Ulema' in Arabic) to help Muslims not break Sharia law. Fiqh is a section of Islamic law which deals with acts of Muslim, that includes both worship and daily life actions.
In Sunni Islam there are four main schools of thought, they are:

The different schools of thought are not different beliefs but different views .
