His ability is complete..
Part of His ability is that:
{...He punishes whom He wills and forgives whom He wills, and Allah is Most Capable of all things.}
[Surat al-Mā’idah: 40]
Allah Almighty says:
{...“He is Capable to send a punishment from above you or from beneath your feet, or split you into factions, and make you suffer at the hands of one another.”...}
[Surat al-An‘ām: 65]
Another aspect of His ability is that He is able to bring and gather us together wherever we may be.
{...Wherever you are, Allah will bring you all together, for Allah is Most Capable of all things..}
[Surat al-Baqarah: 148]
Another aspect of Allah’s perfect ability, of which He informs us, is that He will grasp the earth in His Hand on the Day of Judgment and fold the heavens with His right Hand. Allah Almighty says:
{They did not revere Allah His true reverence. On the Day of Resurrection, the whole earth will be in His Grip, and the heavens will be rolled up in His Right Hand. Glorified and exalted is He above all what they associate with Him!}
[Surat az-Zumar: 67]
