Honouring the homes of Ahlul-Bait

It is incumbent upon the Muslim Ummah to honour and respect the homes of Ahlul-Bait and according to the Ayah mentioned earlier:
"The light (of Allah) shines upon dwellings that are made to be honoured. In those homes men pray to Allah every morning and every afternoon."
These homes are honoured and endeared both physically by being well-kept, and spiritually by being kept pure. Special respect is due to such dwellings.
Sayooti writes in his interpretation of the Qur'an that when this Ayah was revealed, the disciples of the Prophet asked him what was meant by (homes). He replied, "The homes of the Prophets." Then Abu Bakr asked him if the residence of Fatima (A.S.) was among such homes. Prophet Muhammad replied, "Yes, and it is one of the best among them."
Any disrespect towards the homes of the Prophets and the residence of the Final Messenger of Allah is prohibited and considered a transgression upon the person of the Prophet. Such acts lead to apostasy.
Based upon above, If paying homage " Tar'fii' " refers only to the physical appearance of these homes then their well-keeping is a duty of all Muslims. However, if dignifying means doing so in a spiritual capacity, then respecting these dwellings is incumbent upon all Muslims, too.
