The Hadith: 'Angels do not enter a house in which there is a dog'

Q 1: Are the following Hadiths Sahih (authentic)?(A): “Angels do not enter a house in which there is a dog or a picture.” (B) “Accursed! Accursed!” It was said, “Who are they, O Messenger of Allah?” He said, “The player of Duff (a tambourine-like instrument without bells) and the listener to the reed pipe.”

A: (A): The Hadith: “Angels do not enter a house in which there is a dog or a picture.” is Sahih, narrated by Imam Ahmad, Al-Bukhari, Muslim, Al-Tirmidhy, Al-Nasa'y and Ibn Majah. (B): Playing the Duff to announce marriage is permissible for women only, whereas playing and listening to musical instruments and such forms of amusement is prohibited, based on the evidence in the Shari‘ah prohibiting it.As for the Hadith which states, “Accursed! Accursed!...”, it is baseless as far as we know.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
