The blowing of the Trumpet

Abu Muriyyah reports from the Prophet (peace and blessings be upon him); the narrator is in doubt, perhaps the words are: Sayyiduna Abdullah bin Amr (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "The two angels who will blow (the Trumpet) are in the second heaven. The head of one of them is in the east and his feet are in the west (the narrator is in doubt, perhaps the words are:) the head of one of them is in the west and his feet are in the east. Both of them are waiting for when they will be commanded to blow into the Trumpet, so that they blow into it."
Ahmad recorded it with the doubt. If it is from Abu Muriyyah, then it is mursal and its narrators are thiqat (trustworthy); and if it is from Sayyiduna Abdullah bin Amr (may Allah be pleased with him), then it is muttasil (connected) and musnad, and its narrators are thiqat (trustworthy).

Sayyiduna Zayd bin Arqam (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "How can I be at ease, when the angel in charge of the Horn (that is, the Trumpet) has put his mouth to the Horn, has bowed his forehead and is keeping his ear attentive for when he will be commanded?" The Companions of the Prophet (peace and blessings be upon him) heard this, and it weighed very heavily on them. The Prophet (peace and blessings be upon him) said: Say: "Hasbunallahu wa ni'mal wakil (Allah is sufficient for us, and He is the best Disposer of affairs)."
Ahmad and al-Tabarani recorded it; its narrators have been declared trustworthy, although there is weakness in them.

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) reports concerning the saying of Allah Almighty: "When the Trumpet is blown." Sayyiduna Abdullah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: How can I be at ease, when the angel in charge of the Horn (that is, the Trumpet) has put his mouth to the Horn, has bowed his forehead and is waiting for when he will be commanded so that he blows? The Companions of the Prophet (peace and blessings be upon him) submitted: What should we say? The Prophet (peace and blessings be upon him) said: Say: "Hasbunallahu wa ni'mal wakil, 'alallahi tawakkalna (Allah is sufficient for us and He is the best Disposer of affairs; in Allah alone we put our trust)."
Ahmad recorded it, and al-Tabarani recorded it in al-Mu'jam al-Awsat from that Companion in abridged form; its chain contains a narrator, Atiyyah al-Awfi, who is da'if (weak); he has been declared trustworthy, but weakly.

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "Every morning, two angels call out: 'Glorified is the King, the Most Holy.' Two angels call out: 'O Allah, give the one who spends something more in its place, and bring ruin upon (the wealth of) the one who withholds.' Two angels are appointed over the Trumpet; they are both waiting for when they will be commanded, so that they blow. Two angels call out: 'O seeker of good, come forward! O seeker of evil, desist!' And two angels call out: 'Woe to men because of women, and woe to women because of men.'" (Allamah al-Haythami says:) I say: Ibn Majah recorded a part of this narration.
Al-Bazzar recorded it; its chain contains a narrator, Kharijah bin Mus'ab al-Khurasani, who is extremely da'if (weak). Yahya bin Yahya said: He is mustaqim al-hadith (sound in hadith). The remaining narrators of this report are thiqat (trustworthy).

Abdullah bin al-Harith narrates: I was with Sayyidah Aishah (may Allah be pleased with her), and Ka'b al-Ahbar was with her. He mentioned Sayyiduna Israfil (peace be upon him), so Sayyidah Aishah (may Allah be pleased with her) said: O Ka'b, tell me about Sayyiduna Israfil (peace be upon him). Ka'b replied: You people have the knowledge. Sayyidah Aishah (may Allah be pleased with her) said: Yes. Sayyidah Aishah (may Allah be pleased with her) said: But tell me. So Ka'b al-Ahbar said: He has four wings: two wings are in the air, one wing he has wrapped around himself like a garment, and one wing is upon his upper back (kahil); the Pen is on his ear. When revelation descends, the Pen writes, and the angels study it. And the angel appointed over the Trumpet is kneeling on one knee with the other knee raised; he has put the Trumpet to his mouth with his back bent, and he has been commanded that when he sees that Sayyiduna Israfil (peace be upon him) has drawn his wings together, he should blow into the Trumpet. Then Sayyidah Aishah (may Allah be pleased with her) said: I heard the Prophet (peace and blessings be upon him) say it in exactly this way.
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and its chain is hasan (good).
