2 – Clearing one’s throat while praying does not invalidate the prayer, even if the sound produced amounts to two distinct letters, because it is not classed as speech.

3 – It is impermissible to enter anyone’s home without his permission, even if he is one’s closest relative. Allah the Exalted says, “O you who believe, do not enter houses other than your own until you have sought permission and greeted their inhabitants; that is better for you, so that you may take heed” (24:27).

4 – Permission to enter may be given verbally or by customary signal; its form depends on the practice agreed upon between the two parties, and the homeowner’s willingness for the visitor to enter is sufficient.

5 – Maintaining ties between relatives and friends is recommended through visits and gatherings, and the elder or person of standing has the right that people come to him in his own home.

6 – Visits should be made at known, suitable times for entering, socializing, and sitting down. Turning up unannounced, or at times when the household does not wish to receive guests, is what Allah forbade when He said, “O you who believe, do not enter the Prophet’s houses unless permission is granted you … Indeed that was distressing to the Prophet, and he was shy of you, whereas Allah is not shy of the truth” (33:53), as was also indicated in the verse from Surat al-Nur.

7 – It is recommended to perform voluntary prayers at home, for such prayer is a source of light. Al-Bukhari (731) and Muslim (781) relate that the Prophet ﷺ said, “People, pray in your houses, for the best prayer a person performs is in his house—except for the obligatory prayer.”
