Abu Dawud said: Hisham ibn Sa'd and Muhammad ibn Mutarrif narrated it from Zayd, from 'Ata' ibn Yasar, from Abu Sa'id al-Khudri, from the Prophet—peace and blessings be upon him—and the hadith of Abu Khalid is more complete.

1025 — Muhammad ibn 'Abd al-'Aziz ibn Abi Rizmah narrated to us: al-Fadl ibn Musa informed us, from 'Abdullah ibn Kaysan, from 'Ikrimah, from Ibn 'Abbas: that the Prophet—peace and blessings be upon him—called the two prostrations of forgetfulness "the two that humiliate" (al-murghimatayn).

============================================
And al-Nasa'i (1163) via the route of 'Abd al-'Aziz Abu Salamah, all four of them from Zayd ibn Aslam, with it (the same chain). Sulayman and Dawud added in their two narrations according to Muslim: "He prostrates two prostrations before the salutation." It is also in "Musnad Ahmad" (11689), and "Sahih Ibn Hibban" (2664) and (2667). It will come later under number (1026) via the route of Malik ibn Anas, and (1027) via the route of Ya'qub ibn 'Abd al-Rahman al-Qari, both from Zayd ibn Aslam, from 'Ata' ibn Yasar, as mursal (incomplete chain). And those who connected it (with a complete chain) are a group of trustworthy narrators, so the irsal of those who sent it does no harm. Ibn 'Abd al-Barr said in "al-Tamhid" 5/19: "The hadith is connected, musnad, and sound; the shortcoming of those who shortened it in its connection does no harm, because those who connected it are reliable preservers whose addition is accepted, and with Allah is success." And see what will come under number (1029).

His saying: "the two that humiliate Satan" (murghimatay al-shaytan): the origin of this is their saying, "May Allah rub the nose of so-and-so in the dust" (arghama Allah anfa fulan), meaning: He stuck it to the dust (al-rag ham, with the opening of the ra'), which is the earth. Then it was used figuratively for humiliation, inability to retaliate, and submission against one's will. The meaning here is: the two that cause the humiliation of Satan.

(1) Its chain is weak due to the weakness of 'Abdullah ibn Kaysan—who is al-Marwazi—and Ibn 'Adi examined his hadiths from 'Ikrimah, from Ibn 'Abbas, and found them to be unmemorized (ghayr mahfuzah). It was also recorded by Ibn Khuzaymah (1063), Ibn Hibban (2655) and (2689), al-Tabarani in "al-Kabir" (12550), Ibn 'Adi in "al-Kamil" 4/1547, and al-Hakim 1/261 and 324, via the route of al-Fadl ibn Musa, with this chain. And what suffices in its place is what came in the hadith of Abu Sa'id al-Khudri mentioned before it, from his saying—peace and blessings be upon him—"and the two prostrations were the two that humiliate Satan."
