[PyQt] Problem with regex in my code

[Maziar Parsijani]

I want to select 2 "قَالَ" in m = "قَالَتْ قَالَ فَقَالُوا۟ قَالُوا۟ قَالَ
قَالُوٓا۟ قَالَتَا ٱلْقَالِينَ  " but with the below code it selects all
words which contains " "قَالَ"
Now what is the problem here?
I have to put spaces before and after pattern1 for such thing but it
doesn't work for me.

pattern1 = " {0} ".format(self.lineEdit.text())
