On the authority of his father — in the hadith of Abu Ahmad: Shakal ibn Humayd — he said: I said, "O Messenger of Allah, teach me a supplication." He said: "Say: O Allah, I seek refuge in You from the evil of my hearing, and from the evil of my sight, and from the evil of my tongue, and from the evil of my heart, and from the evil of my seminal fluid."(1)

1552 — 'Ubaydullah ibn 'Umar narrated to us, Makki ibn Ibrahim narrated to us, 'Abdullah ibn Sa'id narrated to me, from Sayfi, the freed slave of Aflah, the freed slave of Abu Ayyub, from Abu al-Yasar, that the Messenger of Allah, peace and blessings be upon him, used to supplicate: "O Allah, I seek refuge in You from collapse, and I seek refuge in You from falling from a height, and I seek refuge in You from drowning, and burning, and decrepitude, and I seek refuge in You from Satan assaulting me at the time of death, and I seek refuge in You from dying in Your cause while fleeing, and I seek refuge in You from dying from a snakebite."(2)

(1) Its chain of transmission is sound. Bilal ibn Yahya al-'Absi was declared trustworthy by Abu al-Hasan al-Qattan, and Ibn Ma'in said: "There is no harm in him," which is an expression that, in his usage, equals "trustworthy," as he himself clarified. Waki' is Ibn al-Jarrah, and Bilal is Ibn Yahya al-'Absi, and Shakal is Ibn Humayd al-'Absi.
Al-Nasa'i also recorded it in "Al-Kubra" (7826) via the chain of Waki' ibn al-Jarrah, with this chain of transmission.
Al-Tirmidhi (3798) and al-Nasa'i (7827) also recorded it via two routes from Sa'd ibn Aws, with it. Al-Tirmidhi said: This is a good and rare hadith.
It is also in "Musnad Ahmad" (15541) and (15542).
His statement: "and from the evil of my seminal fluid": it means that seminal fluid overcomes him until he falls into fornication or its preliminaries.

(2) Weak due to its inconsistency, as is made clear in our commentary on the Musnad.
Al-Nasa'i also recorded it in "Al-Kubra" (7917) via the route of al-Fadl ibn Musa, from 'Abdullah ibn Sa'id, with this chain of transmission. It is also in "Musnad Ahmad" (15523).
And see what follows after it.
Al-Sindi said: His statement "from collapse" (al-hadm), with a fatha then a sukun: it is the verbal noun of "demolishing a building": tearing it down. What is meant is "that a building collapse upon me," taking it as a verbal noun with a passive sense, or "that I demolish a building upon someone," taking it as a verbal noun with an active sense.
And his statement "from falling from a height" (al-taraddi): it is falling from a high place to a low one. =
