Dalail al-Khairat is a famous collection of prayers for the Islamic prophet Muhammad, which was written by the Moroccan Sufi and Islamic scholar Muhammad Sulaiman al-Jazuli ash Shadhili (died 1465). It is popular in parts of the Islamic world amongst traditional Muslims - specifically North Africa, the Levant, Turkey, the Caucasus and the South Asia and is divided into sections for daily recitation. The full English translation of the title is (Way-marks of Benefits and the Brilliant Burst of Lights in the Remembrance of Blessings on the Chosen Prophet). To maintain authenticity, this app is based on the version of Dalil al-Khairat, compiled under the supervision of Sheikh Nuh Ha Mim Keller, one of the leading authorities on traditional Islamic sciences.

The legend behind the origin of the Dala’il al-Khayrat is that al-Jazuli once awoke late for his morning prayers and began to look in vain for pure water to perform ritual ablutions. In the midst of his search al-Jazuli encountered a young girl who was aware of al-Jazuli's famed religiosity and was bewildered on why al-Jazuli could not find pure water. The girl then spat into a well which miraculously overflowed with pure sweet water for al-Jazuli to perform ablutions. Consequent to performing prayer, al-Jazuli inquired to the means by which the girl achieved such a high spiritual station. The girl replied it was simply by "Making constant prayer for God to bless the best of creation by the number of breaths and heartbeats." Al-Jazuli then resolved to write a work collecting litanies of prayers asking God to bless and show mercy and kindness to Muhammad.
