سُبْحَانَ ٱللَّٰهِ

The interjection subhanaka ("O Thou who art limitless in Thy glory") stresses here the believer's moral duty to bethink himself of God whenever he is tempted to listen to, or to repeat, a calumny (since every such rumour must be considered a calumny unless its truth is legally proved).
The right course would have been to stop any further currency of false slanders by ignoring them and at least refusing to help in their circulation. The exclamation "Subhanaka", "Praise to Thee (O Allah)", or "Glory to Allah!" is an exclamation of surprise and disavowal as much as to say, "We do not believe it! And we shall have nothing to do with you, O false slanderers!"
