mid-70s soul jam ID (used as a sample)

Hello,

Alas, I can no longer tell you which hiphop artist it was that used one of these two songs as a sample, but it was definitely sampled.
(Well, otherwise I'd have had a look at whosampled.com and that's that!)

I bet this is taken from one of those 7''-only soul tunes...

Thanks in advance for listening and/or identifying in any case.

Since I'm obviously not able to add the 2nd sample to my previous post after I submitted the post, I'll add it in a reply post instead.
