Rasheed was getting suspicious about the relationship she had with Tariq. Why do you believe this was happening ?

Laila would whisper to Aziza about Tariq. Rasheed sometimes refers to Aziza being Tariq's daughter in a sort of sideways manner. Laila just acts as though she didn't understand his implications. Rasheed questions Laila's prior behavior with Tariq, implying something inappropriate had occurred. Rasheed says that if Tariq was alive he would kill him.
