Does the deceased know who visits him and greets him?

Question : The questioner says: Honorable Shaykh, does the deceased feel the visit of his relatives? And does he feel their supplications for him if they are outside the graves or inside them?

Answer : Ibn al-Qayyim (may Allah have mercy on him) mentioned in his book al-Ruh a hadith narrated by Abu Dawud, which Ibn 'Abd al-Barr graded as authentic, and Shaykh al-Islam approved of that, and Ibn al-Qayyim also approved of it: that there is no man who passes by the grave of a man he knew in this world and greets him, except that Allah returns his soul to him so that he returns the greeting.
