Ibrahim ibn Adham (إبراهيم بن أدهم); c. 718 – c. 782 / AH c. 100– c. 165[1]) is one of the most prominent of the early ascetic Sufi saints.
The story of his conversion is one of the most celebrated in Sufi legend, as that of a prince renouncing his throne and choosing asceticism closely echoing the legend of Gautama Buddha. Sufi tradition ascribes to Ibrahim countless acts of righteousness, and his humble lifestyle, which contrasted sharply with his early life as the king of Balkh (itself an earlier center of Buddhism). As recounted by Abu Nu'aym, Ibrahim emphasized the importance of stillness and meditation for asceticism. Rumi extensively described the legend of Ibrahim in his Masnavi. The most famous of Ibrahim's students is Shaqiq al-Balkhi (d. 810).
Abou Ben Adhem (may his tribe increase!)
Awoke one night from a deep dream of peace,
And saw, within the moonlight of his room,
Making it rich, and like a lily in bloom,
...
Religion's gems can ne'er adorn
The flimsy robe by pleasure worn;
Its feeble texture soon would tear,
