(Why express yourself like "Oh my God" when #SubanAllah" gives you more?)

(Why express yourself like "Oh my God"
when "Subhân Allâh" gives you so much more?)

The Messenger of Allâh (صلى الله عليه و سلم) said:

"Is one of you so weak that he cannot acquire
a thousand good deeds everyday?"

So a questioner from amongst those sitting there asked him:
"How can anyone of us gain a thousand rewards?"

He said: "say: (Far is Allâh from imperfection=) Subhân Allâhi
a hundred times, so a thousand good deeds are written for him
or a thousand sins are cancelled for him."
