—any campaign Sultan Ṣalāḥ al-Dīn undertook against the Franks; they were present with him at the liberation of Jerusalem and the coastal towns (1) and elsewhere.
One day al-Malik al-ʿĀdil, Abū Bakr, came to their tent (2) to visit Shaykh Abū ʿUmar, who was standing in prayer. He neither broke off nor shortened his prayer; the Sultan sat down while Abū ʿUmar continued, not even glancing at him until he had completed it—may Allah have mercy on him.
It was Shaykh Abū ʿUmar who first set about building the congregational mosque (3). He began with funds supplied by a private benefactor, but when that money was used up (4) and the walls had already risen to the height of a man, the ruler of Irbil, al-Malik al-Muẓaffar Kūkburī (5), sent additional funds with which the structure was finished. Shaykh Abū ʿUmar was appointed its preacher; he would deliver the sermon wearing his simple clothes, yet radiant with the lights of awe (6), piety, and fear of Allah—Exalted is He. The scent of musk, however well concealed, still betrays itself. At that time the pulpit had three steps, with the fourth serving as a seat, just like the Prophet’s minbar.
Abū al-Muẓaffar (7) relates that he once attended the Friday prayer there, and Shaykh ʿAbd Allāh al-Yūnānī (8) was also present (9). When Shaykh Abū ʿUmar reached the portion of the sermon (10) in which supplication is made for the ruler, he said: “O Allah, set right Your servant al-Malik al-ʿĀdil Sayf al-Dīn Abū Bakr ibn Ayyūb.” At that, Shaykh ʿAbd Allāh al-Yūnānī rose (11), picked up his sandals, left the mosque, and abandoned the Friday prayer.
He said: When we had finished, I went to him and asked, “What did you object to in his words?” He replied, “He calls that oppressor ‘al-ʿĀdil’; I will never pray behind him.” While we were talking Shaykh Abū ʿUmar arrived carrying a loaf of bread and two cucumbers. He broke the loaf and said, “The prayer.” Then he added, “The Prophet—peace and blessings be upon him—said, ‘I was sent during the time of the just king Kisra.’” (12) Shaykh ʿAbd Allāh al-Yūnānī smiled, reached out, and ate. (13) When they had finished, Shaykh Abū ʿUmar rose and departed. After he had gone al-Yūnānī said to me, “My master, this man is nothing but a righteous servant.”
