Abū al-Qāsim al-Dīnawarī. He was a preacher and an ascetic. He used to recite the Qurʾān. He learned Shāfiʿī fiqh from Abū Saʿīd al-Istahrī. He listened to ḥadīth from Najjād. Saymarī also transmitted from him. He was a trustworthy (sīka) and righteous person. He was held up as an example in the struggle against the nafs (nafs mujāhada), truthfulness, chastity, taqwā (God-consciousness), and asceticism. He was among the pioneers in amr bi-l-maʿrūf wa nahy ʿani-l-munkar (enjoining good and forbidding evil). He was also an ideal example in delivering beautiful sermons and in the effect of his sermons on hearts. One day a man brought him 100 dinars to give, but he said, "I do not need this." The man then said, "Then take it and distribute it to your friends." ʿAbd al-Samad said, "Put it on the ground." When the man put it on the ground, ʿAbd al-Samad said to the people gathered there, "Each of you take as much as you need." They took as much as they needed. Shortly after, his son came and complained about some needs at home. ʿAbd al-Samad told his son, "Go to the grocer and buy 115 grams of dates."
One of the neighbors saw him buying a chicken and halwa and began to suspect him. But he saw that ʿAbd al-Samad delivered these items to a widowed woman in need. ʿAbd al-Samad b. ʿUmar earned his living by collecting tobalak herb for herbalists in exchange for a wage. While he was dying, he said, "My master, I have kept you for this moment."
He died on a Tuesday, seven days before the end of the month of Dhu al-Ḥijjah that year. His funeral prayer was performed at the Mansūr Mosque, and he was buried at the cemetery of Imam Aḥmad al-Muzarḥī.
