Maruf Karkhi (Persian: معروف کرخی‎), known also by his full name Abu Mahfuz Maruf Ibn Firuz al-Karkhi, was a Sufi Saint who is a pivotal figure in Sufism. He came from a Christian background and the story of his conversion to Islam is one of the most famous in Islamic lore.

Maruf was born in the district of Wasit or Karkh in Baghdad. His father's name was Firuz, which suggests that he was of Persian origin. His original religion is usually understood to have been Christian, which may mean that the Armenian Islamic preacher and mystic, Farqad Sabakhi, may have mentored Maruf Karkhi.Attar narrates in his Memorial of the Saints that Maruf converted to Islam at a young age at the hands of Ali ibn Musa, after rejecting all forms of polytheism. Tradition recounts that he immediately went and told his father and mother, who rejoiced at his decision and became Muslims themselves. After accepting Islam, Maruf became a student of Dawud Ta'i, and underwent a severe trial of his discipleship. Maruf, however, remained steadfast and proved himself so devout that his righteousness became locally famous.

Shah Hussain (1538–1599) was a Punjabi Sufi poet who is regarded as a Sufi saint. He was the son of Sheikh Usman, a weaver, and belonged to the Dhudha clan of Rajputs. He was born in Lahore (present-day Pakistan). He is considered a pioneer of the Kafi form of Punjabi poetry.

Shah Hussain's love for a Brahmin boy called "Madho" or "Madho Lal" is famous, and they are often referred to as a single person with the composite name of "Madho Lal Hussain". Madho's tomb lies next to Hussain's in the shrine.

His tomb and shrine lies in Baghbanpura, adjacent to the Shalimar Gardens. His Urs (annual death anniversary) is celebrated at his shrine every year during the "Mela Chiraghan" ("Festival of Lights").

Hussain's poetry consists entirely of short poems known as Kafis. A typical Hussain Kafi contains a refrain and some rhymed lines. The number of rhymed lines is usually between four and ten. Only occasionally is a longer form adopted. Hussain's Kafis are also composed for, and have been set to, music deriving from Punjabi folk music. Many of his Kafis are part of the traditional Qawwali repertoire. His poems have been performed as songs by Nusrat Fateh Ali Khan, Abida Parveen and Noor Jehan, among others.
