Dua ] In Islam, ( , plural: ), literally meaning appeal or "invocation", is a prayer of supplication or request. Muslims regard this as a profound act of worship. Muhammad is reported to have said, "Dua is the very essence of worship." There is a special emphasis on du'a in Muslim spirituality and early Muslims took great care to record the supplications of Muhammad and his family and transmit them to subsequent generations. These traditions precipitated new genres of literature in which prophetic supplications were gathered together in single volumes that were memorized and taught. Collections such as al-Nawawi's Kitab al-Adhkar and Shams al-Din al-Jazari's al-Hisn al-Hasin exemplify this literary trend and gained significant currency among Muslim devotees keen to learn how Muhammad supplicated to God. However, Du'a literature is not restricted to prophetic supplications; many later Muslim scholars and sages composed their own supplications, often in elaborate rhyming prose that would be recited by their disciples. Popular du'as would include Muhammad al-Jazuli's Dala'il al-Khayrat, which at its peak spread throughout the Muslim world, and Abul Hasan ash-Shadhili's Hizb al-Bahr which also had widespread appeal. Du'a literature reaches its most lyrical form in the Munajat, or 'whispered intimate prayers' such as those of Ibn Ata Allah. Among the Shia schools, the Al-Sahifa al-Sajjadiyya records du'as attributed to Ali and his grandson, Ali ibn Husayn Zayn al-Abidin. Types and categories Dua is essentially an expression of submission of faith to God and of one's neediness. Type I: Du'a al-mas'alah, or the 'du'a of asking.' This type of du'a is when one asks for the fulfillment of a need, or that some harm be removed from him/her. An example would be when a person asks, "O God! Grant me good in this world, and good in the next life!" Type II: Du'a al-'ibadah''', or the 'du'a of worship.' This type of du'a includes every single act of worship. Examples would include when a Muslim prays or gives zakāt or fasts. Salat The salat is the obligatory prayer recited five times a day, as described in the Quran: "And establish regular prayers at the two ends of the day and at the approaches of the night: For those things, that are good remove those that are evil: Be that the word of remembrance to those who remember (their Lord):" Salat is generally read in the Arabic language; however Imam Abu Hanifah, for whom the Hanafi school is named after, proclaimed that prayer could be said in any language unconditionally. His two students who created the school: Abu Yusuf and Muhammad al-Shaybani, however, did not agree and believed that prayers could only be done in languages other than Arabic if the supplicant can not speak Arabic. Some traditions hold that Abu Hanifa later agreed with them and changed his decision; however there has never been any evidence of this. Hanbali theologian Ibn Taymiyah issued a fatwa proclaiming the same. Until the 1950s, Ismailis from India and Pakistan performed the prayer the language of the local Jama'at Khana. Duas A person who recites from in sura Al Imran till the end of the surah on any night or part of the night, will receive the reward of performing his Salaat for the whole night. A person recites sura Ya Sin early in the morning then his need for the day will be fulfilled. Abdullah bin Masood narrates that Muhammad has stated that the person who recites the last two ayat of sura Al-Baqara till the end, then these two ayats will be sufficient for him, i.e. God will protect him from all evil and ploys.
