[24].Surah An-Nur [The Light]: Ayat 27

২৭. হে মুমিনগন, তোমরা নিজেদের গৃহ ব্যতীত অন্য গৃহে প্রবেশ করো না, যে পর্যন্ত আলাপ পরিচয় না কর এবং গ্রহবাসীদেরকে সালাম না কর। এটাই তোমাদের জন্য উত্তম, যাতে তোমরা স্মরন রাখ।

Ayat 27. O you who believe! Enter not houses other than your own, until you have asked permission and greeted those in them, that is better for you, in order that you may remember.

[Tafseer] of ayat 27. O ye who believe! enter not houses other than your own, until ye have asked permission and saluted those in them: that is best for you, in order that ye may heed (what is seemly). The conventions of propriety and privacy are essential to a refined life of goodness and purity. The English saying that an Englishman's home is his castle, suggests a certain amount of exclusiveness and defiance. The Muslim principle of asking respectful permission and exchanging salutations ensures privacy without exclusiveness, and friendliness without undue familiarity. 

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "If one does not eschew lies and false conduct, Allah has no need that he should abstain from his food and his drink.''

[Al-Bukhari Book 03, Chapter 31, Hadith # 127].

Lesson : This Hadith exhorts those observing Saum to fulfill all the requirements of fasting. One should not conduct himself in such a manner that on the one side he observes Saum and on the other he is fearless of Allah. To save himself from Allah's Wrath and to get the reward of the fasts, one must abstain from all sorts of vices, such as cheating, lying, backbiting, and using obscene language. The threat held against such people in this Hadith should make them fear that their Saum will go waste and they would be deprived of its reward. It does not mean that such people should start eating and drinking during Saum but what is intended is that they should save themselves from all kinds of sins so that they may earn the reward of Saum.
