كما يقال في أثناء الكلام: قال الله تعالى كذا، وقال النبي صلى الله عليه وسلم كذا
For example, a speaker explicitly says that God stated such-and-such or that the Prophet said such-and-such.
In that case the audience is expressly being informed of the separate source. Literary iqtibās, by contrast, integrates recognized wording into a newly composed expression to serve its immediate literary purpose.
The distinction is between attributed reporting and artistic incorporation. The textual origin still needs to be respected and identified accurately when explaining the example.
