That the Messenger of Allah (ﷺ) said: "The angels do no accompany a group among whom there is a dog or a bell."

There are narrations on this topic from Ibn 'Umar, Umm Habibah, and Umm Salamah. This Hadith is Hasan Sahih.
Jami` at-Tirmidhi Book 23, Hadith 34
← Previous Hadith That he heard the Prophet (ﷺ) saying: "Seek your weak for me. For indeed you sustenance and aid is only by your weak."

This Hadith is Hasan Sahih.

Jami` at-Tirmidhi Book 23, Hadith 33 Next Hadith → "The Prophet (ﷺ) sent two armies, place 'Ali bin Abi Talib as the commanded of one of them, and Khalid bin Al-Walid over the other. He said: 'Where there is fighting, then 'Ali (is in command).'" He said: "So 'Ali conquered a fortress and took a slave girl. Khalid wrote a letter and sent me with it to the Prophet (ﷺ), to speak against him for it. So I arrived to the Prophet (ﷺ) to read the letter. The color of his face changed, the he said: 'What do you think about a man who loves Allah and His Messenger, and Allah and His Messenger love him?'" He said: "I said: 'I seek refuge from angering Allah and angering His Messenger, I am only the Messenger.' So he was silent.

There is something about this from Ibn 'Umar. This Hadith is Hasan Gharib, we do not know of it except from the narration of Al-Ahwas bin Jawwab. And his saying: "To speak against him for that." refers to An-Namimah.
