Can anyone find this hadith?

Where the Prophet :saw: said "those who do not show kindness and mercy the younger ones (or younger than oneself?) and do not show respect to the old, is not one of us."

may Allah :swt: reward all of you with continous guidance. Ameen.

And Allah :swt: knows best.

Narrated Abdullah ibn Amr ibn al-'As: The Prophet said: Those who do not show mercy to our young ones and do not realize the right of our elders are not from us (Sunan Abu Dawud).


The Prophet said: He does not belong to us who does not show mercy to our young ones and respect to our old ones, who does not recommend what is reputable and prohibit what is disreputable (Tirmidhi).

In this link it says it is Daif (weak) can any scholar confirm?

EDIT:

http://sunnah.com/abudawud/43/171 Here is a Sahih (sound) one. So basically it is Sahih then.
