7. Power (Al-Qudrah): It is obligatory to believe Allah is attributed with Power, which is defined as an eternal and everlasting Attribute of Allah related to giving existence to and annihilating what is intellectually possible.
Allah said in Surat al-Baqarah, ayah 109:
إِنَّ الله عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ
which means: [Allah has the Perfect Power over all things.] That is, Allah’s Power relates to all things that are intellectually possible.
Hence, the Power of Allah is not related to the intellectually necessary neither in creating nor annihilating, because annihilation does not apply to the intellectually necessary in the first place; and the Power of Allah is not related to the intellectually impossible, neither in creating nor annihilating because existence does not apply to that which is intellectually impossible in the first place.
The fact that the Power of Allah is not related to the intellectually necessary and the intellectually impossible is not powerlessness, but rather indicates the Perfection of Allah.
Note: the Power of Allah is related to the normal impossibilities. For example, although the existence of a sea of mercury is an intellectual possibility, it does not occur, and the Power of Allah is related to it.
