الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ. (al-Fātiḥah 1:2)
All praise belongs to Allah, Lord of all the worlds.
Rabb al-ʿālamīn describes Allah as Lord of all worlds, without restricting His lordship to one kind of creature or a single world.
Thus lordship does not mean merely that Allah nurtures one thing; He is the Sustainer of every world.
