'Alqama said, "A man came to 'Abdullah and said, 'Should I ask permission to go in where my mother is?' He said, 'At all times. Do you want to see her (exposed)?'"

'Ata' said, "I asked Ibn 'Abbas, 'Does one ask permission of one's sister?' He replied, 'Yes.' I repeated it and said, 'My two sisters live in my room and I provide for them and spend on them, so do I ask them for permission?' He said, 'Yes. Do you want to see them naked?' Then he recited, 'O you who believe! Those you own as slaves and those of you who have not as yet reached puberty should ask your permission to enter at three times: before the Dawn Prayer and when you have undressed at noon and after the Night Prayer - three times of nakedness for you.' (24:56) Ibn 'Abbas said, 'He did not command these individuals to ask permission other than at these three times of nakedness.' Then he went on to say, 'The verse in Surat an-Nur:57 is: 'Once your children have reached puberty, they should ask your permission to enter as those before them also asked permission.'"

'Ubayd ibn 'Umayr reported that Abu Musa al-Ash'ari asked permission of 'Umar ibn al-Khattab, but he did not grant him permission. It seemed that he was busy. Abu Musa came back and 'Umar had finished. He said, "Didn't I hear the voice of 'Abdullah ibn Qays? Give him permission to enter." He was told, "He has gone away," so he sent after him. Abu Musa said, "We were commanded to behave like that (i.e. to go away after having asked permission to enter three times)." 'Umar said, "Bring me a clear proof of it." He then went to the gathering of the Ansar and questioned them. They said, "Only the youngest of us will attest to that - Abu Sa'id al-Khudri." He went with Abu Sa'id. 'Umar said, "Is something of what the may Allah bless him and grant him peace,, may Allah bless him and grant him peace, commanded hidden from me? Doing business in the markets distracted me," i.e. going out to trade.

Abu Hurayra said, "When someone comes in and does not say, 'Peace be upon you,' then say, 'No,' until he brings the key which is the greeting (salam)."

'Ubayd ibn Hunayn related to him that Abu Musa said, "I asked permission three times to come in to 'Umar, but he did not give me permission and so I went away. He said, ''Abdullah, is it hard on you to be kept waiting at your door.' I said, 'I asked permission from you three times and you did not give me permission, so I went away (and we were commanded to do that).' 'Umar said, 'From whom did you hear this?' I replied, 'I heard it from the Prophet, may Allah bless him and grant him peace.' 'Umar said, 'Did you hear something from the Prophet, may Allah bless him and grant him peace, which I did not hear? If you do not bring me a clear proof, I will make an example of you!' Therefore I went to a group of Ansar who were sitting in the mosque. I asked them and they said, 'Does anyone doubt this?' I told them what 'Umar had said. They said, 'Only the youngest of us will go with you.' So Abu Sa'id al-Khudri - or Abu Mas'ud - went with me to 'Umar. He said, 'We went out with the Prophet, may Allah bless him and grant him peace, when he was going to Sa'd ibn 'Ubada. He gave the greeting, but Sa'd did not give permission. Then he greeted him a second time and then a third time, but Sa'd did not give him permission. So the Prophet (ﷺ) said, 'We have done what we must.' Then he went back and Sa'd caught up to him and said, 'Messenger of Allah! By the One who sent you with the Truth, every time you greeted me, I heard and answered you, but I wanted to have a lot of greeting (peace) from you for me and the people of my house.'" Abu Musa said, "By Allah, I am a guardian of the hadith of the Messenger of Allah, may Allah bless him and grant him peace." 'Umar said, "Yes, but I wanted to make sure."

Abu'l-'Alaniyya said, "I came to Abu Sa'id al-Khudri and greeted him, but he did not give me permission. Then I greeted him again and he did not give me permission. Then I greeted him a third time, raising my voice and said, 'Peace be upon you, people of the house,' and he did not give me permission. Then I went off to one side and sat down. A slave boy came out to me and said, 'Enter.' I entered and Abu Sa'id said to me, 'If you had said it any more times, I would not have given you permission.' I asked him about vessels (i.e. those used for wine) and other things. He said, 'Haram.' I asked him about an old milk-skin made into a bucket for fermentation purposes. 'Haram,' he said."

Kalda ibn Hanbal reported that Safwan ibn Umayya sent him to the Prophet, may Allah bless him and grant him peace, during the Conquest of Makka with some milk, gazelle, and cucumber. (Abu 'Asim said that the meant vegetables.) The Prophet, may Allah bless him and grant him peace, was at the top of the valley and I did not give the greeting nor ask for permission. He said, "Go back and say, 'Peace be upon you. May I enter?' That was after Safwan had become Muslim."

Jabir said, "When you come in to your family, greet them with a greeting from Allah which is blessed and good." He added, "I only think that it is what is meant by His words, 'When you are greeted with a greeting, greet with one better than it or return it.' (4:86)"

Jabir reported that the Prophet, may Allah bless him and grant him peace, said, "When a man enters his house, he should Allah mention Allah Almighty, both when he enters and he eats. If he does so, Shaytan says (i.e. to the shayatin), 'You cannot spend the night or eat.' When he enters and does not mention Allah when he enters, Shaytan says, 'You have got your lodgings for the night and your supper.'"

Abu Abdul Malik, the mawla of Umm Miskin, the daughter of ('Umar) ibn 'Asim ibn 'Umar ibn al-Khattab, said, "My mistress sent me to Abu Hurayra and he came with me. When he was at the door, he asked in Persian, 'Can we come in?' 'Come in!' she replied.' Then she said, 'Abu Hurayra, if visitors come to me after 'Isha', should I enter into conversation with them?' He replied, 'Converse as long as you have not done the witr prayer. If you have done the witr, there is no conversation after it.'"
