لَا تَسْمَعُ فِيهَا لَاغِيَةً ۞ فِيهَا عَيْنٌ جَارِيَةٌ
No idle speech is heard there; in it is a flowing spring. (88:11–12)
The denial of idle speech describes a moral and social quality of bliss. The flowing spring then adds a physical aspect of well-being. Negation and affirmation together create a more complete picture.
The fronted “in it” makes the Garden salient as the scene of this blessing. Such fronting can focus attention without necessarily creating an absolute exclusive restriction.
