Huston Smith, writes about home in Parabola. He ends with this comment on our final homecoming and what it may be like.
"As to what it will be like, I shall content myself with reporting something I once heard our dear friend and mentor professor (Seyyed Hossein) say in a lecture. He said it is reported in the Islamic tradition that when one enters paradise, for three days the only word one is able to utter, over and over again, is the word "peace."
May it be so!!
