Abu Muhammad Chishti was an early Chishti saint about whose life little is known. He was a disciple of Abu Ahmad Abdal Chishti and the teacher of Abu Yusuf ibn Saman (father of Mawdud Chishti), forming a link in the 'golden chain' leading to Mu'in al-Din Chishti of Ajmer. He died around 411 AH/1020 CE and was buried at Chisht. (Sources: Wikipedia 'Abu Muhammad Chishti'; Chishti silsila sources)
