The Soul:ar-Ruh by Ibn al-Qayyim

In this book, Ibn Qayyem talks about the subject of the soul
in both the material world and in the  Hereafter.
He speaks about the spirits of the living and the dead. He mentions twenty-one
important cases that include such subjects as the awareness of the dead of
visits from the living, the meeting of the  spirits of the dead and the living, the truth
of dreams, the dead visiting each other and remembering their  ng  lives,
the death of the spirit and its immortality, the torture or the bliss of the
grave, the world of souls both in Heaven and in Hell, the difference between the
soul and the spirit, and the status of the soul while asleep and awake and
alive and dead. He discusses the Barzakh (the world of the dead) and where the souls
reside. He writes about other important subjects that cannot be found in any
other book. That is why this scholar is still highly needed especially since people
are in still dire need to know about themselves and their souls. People need to
know about the relationship between the body and the soul and the destiny of
the souls after death, but the fact remains that most people know nothing about
all of these studies. As always, Ibn Qayyem brings every proof from the Quran,
the Sunnah, the consensus of the scholars, the traditions, and the sayings of
the pious forefathers and those who followed them on the straight path. He
supports his arguments with logic and evidence that agree with common sense.
