I was struck by this verse early in the morning while waiting for the fajar prayer
‘And if you speak (the invocation) aloud, then verily, He knows the secret and that which is yet more hidden’ (Taha, Verse 7)
SubhanAllah. Language is said as a social semiotic in Systemic Functional Linguistics theory, which means language is a tool for meaning making besides pictures and sound (Halliday, 1985; Kress and Van Leeuwen, 1996). But, what Allah reveals in this verse is that meaning making is beyond social semiotics, that is, the message or secret intention that lies in you. In simple words, what you utter might not come from the bottom of your heart.
