وَأَنَّهُ تَعَالَى جَدُّ رَبِّنَا
...
And He, exalted be the Jadd of our Lord,
`Ali bin Abi Talhah reported from Ibn `Abbas that he said concerning Allah's statement,
جَدُّ رَبِّنَا
the Jadd of our Lord,
"This means, His actions, His commands and His power."
Ad-Dahhak reported from Ibn `Abbas that he said,
"Allah's Jadd is His blessings, His power and His favor upon His creation."
It has been reported from Mujahid and `Ikrimah that they said,
"It (Jadd) is the magnificence of our Lord."
Qatadah said,
"Exalted is His magnificence, His greatness and His command."
As-Suddi said,
"Exalted is the command of our Lord."
It has been reported from Abu Ad-Darda', Mujahid and Ibn Jurayj that they said,
"Exalted is His remembrance (Dhikr)."
The Jinns Affirmation that Allah does not have a Wife and Children
Allah says,
...
مَا اتَّخَذَ صَاحِبَةً وَلاَا وَلَدًا
He has taken neither a wife nor a son.
meaning, far exalted is He above taking a mate and having children.
This means that when the Jinns accepted Islam and believed in the Qur'an they professed Allah's magnificence above having taken a spouse and a child (or a son).
Then they said,
وَأَنَّهُ كَانَ يَقُولُ سَفِيهُنَا عَلَى اللَّهِ شَطَطًا
