Abū al-ʿAbbās Aḥmad, son of Abū al-Ḥasan ʿAlī b. Aḥmad b. Yaḥyā b. Ḥāzim b. ʿAlī b. Rifāʿa al-Rifāʿī, originally from the Maghrib and later known as al-Baṭāʾiḥī.
His father had come from the Maghrib and settled in the marshlands, in the village of Umm ʿUbayda. There he married the sister of Manṣūr the ascetic, and through her Allah granted him Shaykh Aḥmad and his brothers.
Abū al-Ḥasan was a Quran-reciter who used to lead Shaykh Manṣūr in prayer. He died while his son Aḥmad was still an infant, so the boy was raised by his maternal uncle. It is said that his birth took place at the very beginning of the year 500 AH.
It is related that he once made his disciples swear an oath that, should they notice any fault in him, they would draw his attention to it. Shaykh ʿUmar al-Fārūthī said, “My master, I know of a flaw in you.” (1)
“What is it?” he asked.
He replied, “My master, your flaw is that we are numbered among your companions.” The shaykh and the mendicants wept, whereupon ʿUmar added, “If the ship is sound, it will carry all who are aboard.”
It is said that a cat once fell asleep on Shaykh Aḥmad’s sleeve. When the call to prayer was given he cut the sleeve off rather than disturb the animal; after the prayer he sat down, sewed it back on, and remarked, “Nothing has changed.”
And it is also said that, while he was performing ablution, a mosquito landed on his hand, and he remained motionless until it flew away.
