The Bond of Relationship
Aishah (radi Allahu anha) reported that the Messenger of Allah (sal Allahu alaihi wa sallam) said, “The bond of relationship is suspending from the Throne, and says: ‘He who keeps good relations with me, Allah will keep connection with him, but whosoever severs relations with me, Allah will sever connection with him.”
[Sahih al-Bukhari and Muslim]
The discourse on compassion to relatives mentioned in this Hadith is not impossible because Almighty Allah is Omnipotent and is thus Capable of doing what He likes. He can create perception, consciousness and power of speech in everything. An instance of it has already been mentioned in a Hadith quoted earlier.
And Allah Knows Best!
