Sahih al-Bukhari Book 68, Hadith 49
Allah's Messenger (ﷺ) said, "Shall I tell you of the best families among the Ansar?" They (the people) said,
"Yes, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) said, "The best are Banu- An-Najjar, and after them are Banu
`Abdil Ash-hal, and after them are Banu Al-Harith bin Al-Khazraj, and after them are Banu Sa`ida."
The Prophet (ﷺ) then moved his hand by closing his fingers and then opening them like one throwing
something, and then said, "Anyhow, there is good in all the families of the Ansar. "
Allah's Messenger (ﷺ) said, The example of a miser and a generous person is like that of two persons wearing iron cloaks from the breast upto the neck When the generous person spends, the iron cloak enlarges and spread over his skin so much so that it covers his fingertips and obliterates his tracks. As for the miser, as soon as he thinks of spending every ring of the iron cloak sticks to its place (against his body) and he tries to expand it, but it does not expand. The Prophet (ﷺ) pointed with his hand towards his throat.
(a companion of Allah's Messenger (ﷺ)) Allah's Messenger (ﷺ), holding out his middle and index fingers, said, "My advent and the Hour's are like this (or like these)," namely, the period between his era and the Hour is like the distance between those two fingers, i.e., very short.
