*The one seeking permission should not enter the house if there is no one in it, for this is a clear sign of transgression.
*After one is given permission to enter a home, one should wait for a short period of time before entering, and seek permission once more. Abu Wa’il, may Allah have mercy on him, said: ‘We went to Ibn Masood () after we finished performing the prayer. We greeted him from the door, and he gave us permission to enter. We stood by the door for a short period of time, and the servant came to us and she said: ‘Will you not enter?’ We then entered and found him sitting, remembering Allah. He asked us: ‘What prevented you from entering, when I gave you permission to enter?’ We said: ‘We thought that some of your family was sleeping…’ (Al-A’daab ash-Shari’yah 1/428) *Whoever sends a messenger to call someone does not need to seek permission to enter the home. The Prophet () said:
'If one of you is invited to a have a meal and he comes with the servant who called him, this is his permission to enter the home.'(Abu Dawood)
Some scholars state that one should seek permission to enter their home if they come late.
*One should seek permission when he wants to get up and leave the sitting. Ibn Umar () said that the Messenger of Allah () said:
'If one of you visits his brother and then sits beside him, let him not stand up to leave until he seeks permission.'(As-Silsilah as-Saheehah) *One should seek permission to enter upon one's sister, and mother.
