The Prophet said, "The young should greet the old, the passer by should greet the sitting one, and the small group of persons should greet the large group of persons. "

I used to greet the Prophet while he was in prayer and he would return my greeting, but when we returned (from Ethiopia) I greeted the Prophet (while he was praying) but he did not return the greeting, and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious matter)."

[Al-Bukhari and Muslim].

The narration in Al-Bukhari adds: The Messenger of Allah (PBUH) said, "The young should greet the elderly.''

Allah's Apostle said, "The riding one should greet the walking one, and the walking one should greet the sitting one, and the small number of persons should greet the large number of persons."

Allah's Apostle said, "The riding person should greet the walking one, and the walking one should greet the sitting one, and the small number of persons should greet the large number of persons."

Allah's Apostle said, "The younger person should greet the older one, and the walking person should greet the sitting one, and the small number of persons should greet the large number of persons."

We used to greet the Prophet while he used to be in prayers, and he used to reply to our greetings. But when we came back from Najashi (the King of Ethiopia) we greeted him (while he was praying) and he did not reply to us. We said, "O Allah's Apostle! We used to greet you in the past and you used to reply to us." He said, "Verily The Mind is occupied and busy with more important matter during the prayer." (So one cannot return One's greetings.)

Allah's Apostle sent me for some job and when I had finished it I returned and came to the Prophet and greeted him but he did not return my greeting. So I felt so sorry that only Allah knows it and I said to myself,, 'Perhaps Allah's Apostle is angry because I did not come quickly, then again I greeted him but he did not reply. I felt even more sorry than I did the first time. Again I greeted him and he returned the greeting and said, "The thing which prevented me from returning the greeting was that I was praying." And at that time he was on his Rahila and his face was not towards the Qibla.

The Prophet came from the direction of Bir Jamal. A man met him and greeted him. But he did not return back the greeting till he went to a (mud) wall and wiped his face and hands with its dust (performed Tayammum) and then returned back the greeting.

The Prophet (saws) said: If any one of you greets me, Allah returns my soul to me and I respond to the greeting.

We used to greet the Prophet while he was praying and he used to answer our greetings. When we returned from An-Najashi (the ruler of Ethiopia), we greeted him, but he did not answer us (during the prayer) and (after finishing the prayer) he said, "In the prayer one is occupied (with a more serious matter)."

Whenever Allah's Apostle greeted somebody, he used to greet him three times, and if he spoke a sentence, he used to repeat it thrice.

[Al-Bukhari and Muslim].

A man wearing two red garments passed the Prophet (saws) and gave him a greeting, but he did not respond to his greeting.

Yahya related to me from Malik from Zayd ibn Aslam that the Messenger of Allah, may Allah bless him and grant him peace, said, "The one riding greets the one walking, and when one of a group of people gives a greeting, it is enough for all of them."

`Aisha said that the Prophet said to her "O `Aisha' This is Gabriel and he sends his (greetings) salutations to you." `Aisha said, "Salutations (Greetings) to him, and Allah's Mercy and Blessings be on him," and addressing the Prophet she said, "You see what I don't see."

Yahya related to me from Malik from Ibn Shihab from Said ibn al- Musayyab, and from Abu Salama ibn Abd ar-Rahman, the same as that.

Malik said, "Every forgetfulness which decreases from the prayer, prostrations for it come before the greeting, and every forgetfulness which is an addition to the prayer, prostrations for it come after the greeting."

Allah's Apostle talked to his companions about his Night Journey to the Heavens. When he reached the fifth Heaven, he met Aaron. (Gabriel said to the Prophet), "This is Aaron." The Prophet said, "Gabriel greeted and so did I, and he returned the greeting saying, 'Welcome, O Pious Brother and Pious Prophet."

The Prophet said, "Allah created Adam in His picture, sixty cubits (about 30 meters) in height. When He created him, He said (to him), "Go and greet that group of angels sitting there, and listen what they will say in reply to you, for that will be your greeting and the greeting of your offspring." Adam (went and) said, 'As-Salamu alaikum (Peace be upon you).' They replied, 'AsSalamu-'Alaika wa Rahmatullah (Peace and Allah's Mercy be on you) So they increased 'Wa Rahmatullah' The Prophet added 'So whoever will enter Paradise, will be of the shape and picture of Adam Since then the creation of Adam's (offspring) (i.e. stature of human beings is being diminished continuously) to the present time."

Yahya related to me from Malik from Ishaq ibn Abdullah ibn Abi Talha that Anas ibn Malik heard Umar ibn al-Khattab return the greeting of a man who greeted him. Then Umar asked the man, "How are you?" He said, "I praise Allah to you." (Ahmadu ilayka Allah) Umar said, "That is what I wanted from you."

The Prophet said, "Allah created Adam, making him 60 cubits tall. When He created him, He said to him, "Go and greet that group of angels, and listen to their reply, for it will be your greeting (salutation) and the greeting (salutations of your offspring." So, Adam said (to the angels), As-Salamu Alaikum (i.e. Peace be upon you). The angels said, "As-salamu Alaika wa Rahmatu-l-lahi" (i.e. Peace and Allah's Mercy be upon you). Thus the angels added to Adam's salutation the expression, 'Wa Rahmatu-l-lahi,' Any person who will enter Paradise will resemble Adam (in appearance and figure). People have been decreasing in stature since Adam's creation.

That the Prophet talked to them about the night of his Ascension to the Heavens. He said, "(Then Gabriel took me) and ascended up till he reached the second heaven where he asked for the gate to be opened, but it was asked, 'Who is it?' Gabriel replied, 'I am Gabriel.' It was asked, 'Who is accompanying you?' He replied, 'Muhammad.' It was asked, 'Has he been called?' He said, 'Yes.' When we reached over the second heaven, I saw Yahya (i.e. John) and Jesus who were cousins. Gabriel said, 'These are John (Yahya) and Jesus, so greet them.' I greeted them and they returned the greeting saying, 'Welcome, O Pious Brother and Pious Prophet!;' "

Yahya related to me from Malik from Abdullah ibn Dinar that Abdullah ibn Umar said that the Messenger of Allah, may Allah bless him and grant him peace, said, "When a jew greets you, and says 'Death to you' (as-samu alaykum) say, 'And to you.' "

Yahya said, "Malik was asked whether a person who greeted a jew or christian, should apologise for it. He said, 'No'."
