Sahih Muslim Book 39, Hadith Number 6714.

Chapter : The question of a Jew from Allah’s Messenger (may peace be upon him) about soul and his words: “They ask thee about the soul”.

Abdullah reported that Allah’s Apostle (may peace be upon h@) was reclining against a tree in the garden. The rest of the hadith is the same, but there is a slight variation of wording.
