[15].Surah Al-Hjir [The Rocky Tract]: Ayat 66-69

Ayat 66. And We made known this decree to him, that the root of those (sinners) was to be cut off in the early morning.

Ayat 67. And the inhabitants of the city came rejoicing (at the news of the young men's arrival).

Ayat 68. [Lout (Lot)] said: "Verily! these are my guests, so shame me not.

Ayat 69. "And fear Allah and disgrace me not." 

Hazrat Abu Shuraih Khuwailid bin Amr Al-Khuza'i (May Allah be pleased with him) reported: I heard Messenger of Allah  [SAWW](PBUH) saying, "He who believes in Allah and the Last Day, should accommodate his guest according to his right.'' He was asked: "What is his right, O Messenger of Allah?'' He  [SAWW](PBUH) replied: "It is (to accommodate him) for a day and a night, and hospitality extends for three days, and what is beyond that is charity.''

it is added: Messenger of Allah  [SAWW](PBUH) said, "It is not permissible for a Muslim to stay so long with his brother till he makes him sinful.'' He was asked: "O Messenger of Allah, how can he make him sinful?'' He replied, "He prolongs his stay with him till nothing is left with the host to entertain him (guest).''

[Muslim Book.18, Chapter 13, Hadith # 4287]. 

Lesson : as mentioned above in Surah Al-Hjir Ayat. "Verily! these are my guests, so shame me not. This Hadith throws light on something more of the etiquette and scope of hospitality. A guest ought to be given the best entertainment on the first day and night. For the next two days, hospitality should be moderate. On the fourth day, the guest should leave for his destination. Yet if he chooses to stay, hospitality will be in the sense of charity.
