"this pain or illness is a punishment that afflicted some nations before you, [or a group from the Children of Israel], and then it remained on the earth, coming and going. So whoever hears of it in a land should not go there, and if it occurs in a land while he is there, he should not leave fleeing from it." This is an authentic ḥadīth, narrated from Usāmah ibn Zayd, Saʿd ibn Abī Waqqāṣ, ʿAbd al-Raḥmān ibn ʿAwf, and others. 1 - As for the ḥadīth of Usāmah, there are several chains from him: the first is from ʿĀmir ibn Saʿd ibn Abī Waqqāṣ from him in the second narration. It was recorded by al-Bukhārī (6974) and Muslim (7/26-30), with the additional context for him, and also by Mālik (3/91) and from him by the two Shaykhs, as well as Abū ʿAmr al-Dānī in "al-Fitan" (p. 43/1), al-Nasāʾī in "al-Sunan al-Kubrā" (4/362/7524), ʿAbd al-Razzāq in "al-Muṣannaf" (11/146/20158), and from him by Aḥmad (5/207), al-Ḥumaydī in "Musnad" (249/544), and also by Aḥmad (5/200-201, 202, 208), as well as al-Dānī (p. 42/2) and al-Ṭabarānī in "al-Muʿjam al-Kabīr" (1/92-94, 124) through various chains from him. Al-Ḥumaydī added: "ʿAmr ibn Dīnār said: Perhaps for some people it is a punishment or affliction, and for others, it is martyrdom. Sufyān said: I was impressed by this statement of ʿAmr." The second: from Ibrāhīm ibn Saʿd who said: I heard Usāmah ibn Zayd narrate it. It was recorded by al-Bukhārī (5728) - with the context for him in the first narration - and Muslim (7/28), Aḥmad (1/178, 5/206, 209, 210), and al-Dānī (42/1-2) through various chains from him
