Question:
Muhammad Iqbal (Urdu: mHmd iqbl) (November 9, 1877 - April 21, 1938), widely known as Allama Iqbal, was a poet, philosopher, and politician, as well as an academic, barrister and scholar in British India who is widely regarded as having inspired the Pakistan Movement. He is called the "Spiritual Father of Pakistan." He is considered one of the most important figures in Urdu literature, with literary work in both Urdu and Persian.
Iqbal, after completing his Master of Arts degree in 1899, began his career as a reader of Arabic at Oriental College and shortly afterwards was selected as a junior professor of philosophy at Government College Lahore, where he had also been a student in the past. He worked there until he left for England in 1905. In 1908, he returned from England and joined the same college again as a professor of philosophy and English literature. In the same period Iqbal began practising law at Chief Court Lahore, but he soon quit law practice and devoted himself in literary works, becoming an active member of Anjuman-e-Himayat-e-Islam. In 1919, he became the general secretary of the same organisation. Iqbal's thoughts in his work primarily focus on the spiritual direction and development of human society, centred around experiences from his travels and stays in Western Europe and the Middle East. He was profoundly influenced by Western philosophers such as Friedrich Nietzsche, Henri Bergson and Goethe.  The poetry and philosophy of Mawlana Rumi bore the deepest influence on Iqbal's mind. Deeply grounded in religion since childhood, Iqbal began concentrating intensely on the study of Islam, the culture and history of Islamic civilisation and its political future, while embracing Rumi as "his guide". Iqbal would feature Rumi in the role of guide in many of his poems. Iqbal's works focus on reminding his readers of the past glories of Islamic civilisation, and delivering the message of a pure, spiritual focus on Islam as a source for socio-political liberation and greatness. Iqbal denounced political divisions within and amongst Muslim nations, and frequently alluded to and spoke in terms of the global Muslim community or the Ummah.  Iqbal's poetry has been translated into many European languages, at the time when his work was famous during the early part of the 20th century. Iqbal's Asrar-i-Khudi and Javed Nama were translated into English by R. A. Nicholson and A. J. Arberry respectively.

Answer the question at the end by quoting:

Nightwish is a symphonic metal band from Kitee, Finland. The band was formed in 1996 by lead songwriter and keyboardist Tuomas Holopainen, guitarist Emppu Vuorinen, and former lead singer Tarja Turunen. The band soon picked up drummer Jukka Nevalainen, and then bassist Sami Vanska after the release of their debut album, Angels Fall First (1997). In 2001, Vanska was replaced by Marco Hietala, who also took over the male vocalist role previously filled by Holopainen or guest singers.
Earlier Nightwish performs symphonic metal with soaring female operatic vocals. Their music has been described as "bombastic heavy, symphonic and cinematic, with keyboards and strings creating a gothic atmosphere". They have also been known to play power metal and gothic metal.  The band's music is also known to be complex and layered. Their approach is epic, theatrical and operatic. Critic Chad Bowar notes that the music is "always very melodic with memorable choruses and a lot of hooks."  The usage of a female vocalist has become a sort of trademark, though less so since the outbreak of new female fronted metal bands in the mid-2000s with the popularization of bands such as Evanescence and Leaves' Eyes as well as several gothic metal bands mixing female and male vocals, such as Lacuna Coil, Tristania, Epica and the early Within Temptation.  Bassist and vocalist Marco Hietala describes the style of the band's music as "melodic symphonic metal;" though this is not a view shared by all members of the group, including band composer Tuomas Holopainen, who describes the band as simply symphonic metal. Some critics find that the band had a gothic sound since their debut. The music of Nightwish had been "distinguished by the operatic voice" of soprano Tarja Turunen, a "charismatic frontwoman with a powerful voice". Critics observed that her vocals became less operatic with the release of Once. Following the departure of Tarja Turunen from the group, Nightwish left behind the "signature operatic vocals" of their earlier albums.  While the music of Nightwish is centered around a female lead singer, the band has also featured some male vocals on their albums ever since their debut release Angels Fall First. This debut album also included "elements of folk music and ambience" that were discarded on their subsequent album Oceanborn. However, the song "Creek Mary's Blood" from the album "Once" featured some use of folk-oriented Native American melodies, and their 2007 release Dark Passion Play featured folk music elements on the songs "The Islander" and "Last of the Wilds".

What have been their major musical influences?
The band's music is also known to be complex and layered. Their approach is epic, theatrical and operatic.
