Finding an extra pair of sleeves after purchasing an unstitched garment

Q: I purchased an unstitched ladies suit (shalwar qameez) from a shop 3 years ago. Recently when I gave it to tailor for stitching, she discovered that it had an extra pair of sleeves. What should I do with that extra pair of sleeves? Can I give some money for that extra piece of cloth to any poor person and use the cloth myself?

Verification of Ahaadith

Q: Please verify these two Hadith:

1. I'm Arab but Arab is not in me and I'm not Hind but Hind is in me.

2. I feel a cool breeze coming from Hind.

Did Nabi (Sallallahu Alayhi Wasallam) really say that? If yes then please tell me the tafseer but not in Arabic.
