From the magnificent book ?Silsilah al-Ahaadeeth as-Saheehah wa shai min fiqhihaa was fawaaidihaa? by the Noble Imaam, the Mujaddid, the Mujaahid, the Muhaddith Abu Abdur Rahmaan Muhammad Naasir ud-Deen al-Albaanee (rahimahullaah).
Hadeeth No. 182, Page 354.
quote:
From the Etiquettes of Visiting Brothers.
?When one of you visits his brother and then sits with him, let him not stand (to leave) until he asks his permission.?
Reported by Abu Shaikh in ?Taareekh Asbahaan? (113), that Ishaaq bin Muhammad bin Hakeem narrated to us, that Yahyaa bin Waaqid narrated to us saying, Ibn Abi Ghaneeyah narrated to us saying, my father narrated to us saying, Jublah bin Saheem narrated to us from Ibn Umar who said, the Prophet (sallallaahualaihi wasallam) said, ??and he mentioned the hadeeth??
I say the chain is saheeh and all its narrators are well known.
The Shaikh then discusses each of the narrators and establishes their trustworthiness and truthfulness. The Imaam us-Sunnah then says,
quote:
The hadeeth contains a notification of a lofty etiquette which is that the visitor should not stand until (and after) he seeks permission from the one being visited. And many people in some Arab countries have abandoned this noble Prophetic guidance, so you find them leaving a gathering without seeking permission. And not only this, rather they leave without giving salaam as well.
And this is in opposition to another Islamic etiquette which is shown by the next hadeeth?
Hadeeth No. 183, Page 356.
quote:
?When one of you approaches a gathering then let him give salaam and when he wishes to stand (to leave) then let him give salaam, for the first (salaam) is no less important than the other.?
Reported by al-Bukhaaree in ?al-Adab al-Mufrad? (1012 and 989), Abu Dawood (5208), at-Tirmidhee (2/118), an-Nasaaee in ?Amal-ul-yawm wal-laylah? (and others which the Shaikh mentions) from Ibn Ajlaan, from Saeed al-Maqbaree, from Abu Hurayrah in marfu? form and at-Tirmidhee said its chain is hasan.
I say its chain is good and its narrators are all trustworthy.
The Haafidh and Imaam, then discusses some of the narrators and some of the supporting chains.
He then says,
quote:
Giving salaam upon standing from a gathering is an etiquette which has been abandoned in many countries and those upon whom it is the greatest duty to revive it are the people of knowledge and its students. So it is necessary for them upon entering a classroom of students, for example, to give salaam and to do the same when they leave, for the first (salaam) is not more deserving to be done than the other.
And that is from spreading the salaam which has been ordered in the next hadeeth.
