Ali in Muslim culture
Except for Muhammad, there is no one in Islamic history about whom as much has been written in Islamic languages as Ali. Ali is widely revered and honored by Muslims. Almost every Sufi order traces its origin to Muhammad through Ali. Having been one of the first Muslims and foremost Ulema (Islamic scholars), he was extremely knowledgeable in matters of religious belief and Islamic jurisprudence, as well as in the history of the Muslim community. He was known for his bravery and courage. Muslims honor Muhammad, Ali, and other pious Muslims and add pious interjections after  their names. Ali's birthday is celebrated on 13th of Rajab by Shia Muslims to remember their first Imam who was born in the House of Allah/Kaaba. His death is remembered and mourned from the 19 to 21st of Ramadan which is the anniversary of his assassination and martyrdom. The "ziyarat" of the Tomb of Imam Ali in the Imam Ali Mosque is a usual religious tradition among Shias and Sufis. At the Ali Masjid in Pakistan is a huge boulder which carries the marks of a hand believed to be that of Ali. In India the Moula-Ali  Darga or mortuary was built in the memory of Ali about 15 Kilometers from Secunderabad. There is an annual event Moula-ali Urs that takes place during the month of Moharram and people gather there. Ali has high position in the mind of Muslims and they made a lot of pictures, poems and myths about him. For example, "Ali Guyam, Ali Juyam" (I call Ali, I seek Ali) is a famous rhyme in Iran. He is the main protagonist in the epic poem Utendi wa Tambuka, dated 1728 - one of the earliest known documents in the Swahili language, which is  considered a classic of that culture. The Gupti Ismaili community also holds that Imam ‘Ali and his descendants through Isma’il b. Ja’far, collectively, are the tenth and final "avatāra" expected by several South Asian religions, and represent the continuity of divine guidance to humankind. In the view of some Guptis, this is corroborated by the Quranic verse 14:4 which mentions the idea that God had sent a messenger to every land. They understand the "avatāras" to be these messengers sent by God to their people in the Indian Subcontinent. The important Ismaili "ginān Caution for the Faithful" ("Moman Chetāmaṇī"), a  foundational piece of literature for the Guptis of Bhavnagar and composed by Imamshah, alludes to the status of "avatāra" held by ‘Ali:“The descendants of ‘Ali and the Prophet continued Generation upon generation He who forsakes his veneration to them Approaches the gates of Hell Know that he will be considered the worst of the damned The vision of whose face will be a heinous sin A soul who shall destroy his own mother and father A soul that does not recognize the present garb of the avatāra.” Poems. Sufis have glorified Ali in their works. For example, Rumi says in  Masnavi: The man spat in Ali's pure face, the pride of every saint and prophet far and wide The moon itself prostrates before this face... Sufis recite "Manqabat" Ali in the praise of Ali (Maula Ali), after "Hamd" and "Na`at" in their "Qawwali".
