From Sahih Muslim (Hadith 6189):
Abu Sa'id Khudri reported Allah's Messenger (ﷺ) as say ing:While I was asleep I saw people being presented to me (in a dream) and they wore shirts and some of these reached up to the breasts and some even beyond them. Then there happened to pass 'Umar b. Khattab and his shirt had been trailing. They said: Allah's Messeneer, how do you interpret the dream? He said: (As strength of) faith
