Is he out in this heavy rain?

In the previous chapter, we read that Kashif was talking to Salman, a stranger to him then he received a call from Sana, she was worried a lot when Kashif told him that he was in the hospital she said :

Sana: What? In the hospital? Are you fine? What happened?

Kashif: Wait! Wait, don't you worry, nothing happened to me. I came due to a kid. I will tell you the rest when I will return.

Sana: Thank goodness Alhumdulillah. And I also want to inform you that It's been an hour since Kamran has gone...

Kashif: (cutting the statement) What!? What do you mean? When did he come back? Where is he gone now?

Sana: You always talk in between! So the thing is he came back home in the evening. Then when I told him that you are out since he left he got worried and left to find you, now it has been an hour since he left.

Kashif: What do you mean? Is he out in this heavy rain?

Sana: Yes! But you can do one thing

Kashif: What?
