الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ
All praise belongs to Allah, Lord of all worlds. (Al-Fatihah 1:2)
The plural “الْعَالَمِينَ” has the form conventionally associated with rational beings, although divine lordship includes far more than people alone. The source explains a predominance of rational forms within broad reference.
The grammatical form must not be used to narrow the meaning so that other created worlds are excluded.
