Muhammad is reported to have said, "Dua is the very essence of worship," while one of God's commands expressed through the Quran is for them to call out to Him:

And your Lord says: "Call on Me; I will answer your (Prayer):
— Quran, surah 40 (Ghafir), ayah 60[2]

There is a special emphasis on du'a in Muslim spirituality and early Muslims took great care to record the supplications of Muhammad and transmit them to subsequent generations.[citation needed] 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.
