I have read this online, can't remember the link, but I copied the text. Its the translation of a hadith:
Some people will come on the Day of Judgement and their Imaan will be outstanding, it’s light will shine from their chests and from their right hands. So it will be said to them, Glad tidings for you today, Assalamu ‘alaikum and Goodness for you, Enter into it (Jannah) forever!’ So the Angels and the Prophets will be jealous of the Love of Allah for them.
So the Sahabah asked, “Who are they, Ya Rasoolullah?” He [sws] replied,
They are not from us and they are not from you. You are my companions but they are my beloved.
