Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: “Allah Almighty created Adam (peace be upon him) in his form, his height was sixty cubits. When Allah Almighty created him, He said: Go and greet that group of angels who are sitting, and listen carefully to what they reply to you, for indeed these (words) will be the greeting for you and your offspring. (He went and) said: As-salamu ‘alaykum (peace be upon you). They replied: As-salamu ‘alayka wa rahmatullah (peace be upon you and the mercy of Allah), thus adding the words ‘wa rahmatullah’. When a man enters Paradise, he will enter in the form (and stature) of Adam (peace be upon him). But (from the birth of Adam) until today, the stature has been decreasing.”
