What are the Mutawatir and Sahih hadiths that mention the soul, with references?

The successive (mutawatir) hadiths agree on several unseen matters related to the soul after death, including:

1. The survival of souls: Souls do not perish with the perishing of bodies. Whoever claims their perishing has defied explicit hadiths and the apparent meaning of the Quran. The hadiths about the bliss and torment of souls after separation also indicate this. 2. The return of the soul to the body at the time of questioning: The soul returns to the body at the time the two angels question in the grave, as stated in the hadith of Al-Bara' bin 'Azib. 3. The presence of souls at the gravesites: Souls are present at the gravesites. This is evidenced by hadiths about showing the deceased his place, his hearing the footsteps, and the Muslim's greeting to the graves. 4. Grave torment for both soul and body: The torment in the grave affects both the soul and the body together, and it may affect them individually. This is affirmed by the explicit, successive Sunnah.

For more details, it is recommended to refer to the book "Al-Ruh" (The Soul) by Ibn Al-Qayyim.
