Contagion, the hamah, evil omens and other matters

Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "There is no reality to the contagion of disease, to evil omens or to envy, and the evil eye is real."
Imam Ahmad recorded it. Its chain contains Rishdin bin Sa'd, and he is da'if (weak), though he has also been declared trustworthy. The rest of its narrators are thiqat (trustworthy).

Sayyiduna Ali (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "There is no significance to Safar (the month being ill-omened) or to the hamah, and a sick person does not pass on (illness) to a healthy one."
Imam Abu Ya'la recorded it. Its chain contains Tha'labah bin Yazid al-Himmani, whom Imam al-Nasa'i (may Allah have mercy on him) declared thiqah (trustworthy), yet there is weakness in him. The rest of its narrators are thiqat (trustworthy).

Abu Talhah al-Khawlani narrates: Once Umayr bin Sa'd was sitting among some people of Palestine, and he used to be called "nasij wahdihi" (one of a kind). He sat on a large bench of his in his house and said to his slave: O boy, take the horses to water! The narrator says: In the house there was a stone trough. So he took them to water. Then he asked: Where is so-and-so (a mare)? He said: She has mange and is dripping blood (or he said: dripping water); the narrator Abu Ishaq is in doubt about this. He said: Take her to water as well. One of those present said: In that case all the horses will catch mange. He said: Take her to water, for I heard the Prophet (peace and blessings be upon him) say: "There is no reality to contagion, to evil omens or to the hamah. Have you not seen the camel that is in the desert, and in the morning there is an affliction in its chest (or in its belly) which it did not have before? So who infected the first one?"
Imam Abu Ya'la recorded it, and Imam al-Tabarani recorded it in abridged form. Its chain contains Isa bin Sinan al-Hanafi, whom Ibn Hibban and others declared thiqah (trustworthy), while Imam Ahmad and others graded him da'if (weak). The rest of its narrators are thiqat (trustworthy).

Sayyiduna Anas (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: "There is no significance to the contagion (of disease) or to the hamah; who infected the first one?"
(Allamah al-Haythami says:) I say: In the "Sahih" this part of it is recorded: "There is no significance to contagion."
Imam al-Bazzar recorded it, and its narrators are the narrators of the Sahih, except Ali bin al-Husayn al-Dirhami, and he is thiqah (trustworthy).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet (peace and blessings be upon him) said: "There is no significance to the contagion (of disease)." A Bedouin said: "O Messenger of Allah! Sometimes we take a mangy goat and leave it among the goats, and then all the goats become mangy." The Prophet (peace and blessings be upon him) asked: "O Bedouin! Who gave mange to the first one?"
Imam al-Tabarani recorded it with several chains, and the narrators of some of them are the narrators of the Sahih.

Abu Talhah al-Khawlani narrates: We came to Sayyiduna Umayr bin Sa'd (may Allah be pleased with him); we were a group of people from Palestine. I mentioned the contagion of disease in his presence, and he said: I heard the Prophet (peace and blessings be upon him) say: "There is no significance to contagion (of disease), to evil omens or to the ham."
Imam al-Tabarani recorded it, and Imam Abu Ya'la recorded it as well, with a long story in it. Its chain contains Isa bin Sinan al-Hanafi, whom Ibn Hibban and others declared thiqah (trustworthy), while Imam Ahmad and others graded him da'if (weak). The rest of its narrators are thiqat (trustworthy).

Sayyiduna Abu Umamah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "There is no significance to contagion (of disease), to Safar (the month being ill-omened) or to the ham, and two months never (consecutively) complete thirty days." (Allamah al-Haythami says:) I say: From this Companion,
this narration will come in a more complete form in the chapter on blood money (diyat), in the chapter concerning one who kills a dhimmi.
Imam al-Tabarani recorded it. Its chain contains Amr bin Muhammad al-Ghaz, and I do not know him, and Abd al-Rahman bin Thabit bin Thawban, whom Ibn Hibban and others declared thiqah (trustworthy), while Imam al-Nasa'i (may Allah have mercy on him) and others graded him da'if (weak). The rest of its narrators are thiqat (trustworthy). (Allamah al-Haythami says:) I say: Some hadith about evil omens will come later, along with what a person should say at that time.
