— Ishāq ibn Ibrāhīm* ibn Masarra, Abū Ibrāhīm al-Tujībī * (repeated 61), known as al-Ṭulayṭulī, the ascetic. He was one of the eminent figures of Córdoba, where he traded in linen. He combined knowledge with practice and never hesitated to speak the truth for Allah’s sake. A jurist whose advice was sought, he kept to himself, commanded respect, and inspired awe.
Al-Mustanṣir Billāh al-Ḥakam treated him with great courtesy and respect. Al-Ḥakam once sent him a note that read:
“May Allah preserve you, protect you, guide you, and watch over you. When the Commander of the Faithful—my lord, may Allah keep him for the friends of Allah through whom one seeks support—tested you by advancing you in office while delaying your stipend, he also sent you a private summons so that you might share in the joy that he was experiencing. I, too, delivered the summons on my own behalf as an added mark of honour. Yet despite all of this you absented yourself, to a degree that leaves you little room for excuse. The Commander of the Faithful has taken full note of your refusal and reproaches you for it. What, then, caused you to hold back from answering his invitation? Let me know.”
Abū Ibrāhīm replied: “Peace be upon the emir, my master, and the mercy of Allah. My hesitation was not on my own account; rather, it was for the sake of the Commander of the Faithful.” He went on to say a few words by which his excuse was accepted.
