Sayyidi wa sandi Shaikh Mufti Mohammad Taqi Usmani(Allah preserve him) mentioned,

There is growing trend of Islamic awareness and practicing in younger generation. This often leads to clash with their non practicing parents. Sometimes the situation becomes ugly. It is imperative to be firm on the religious commandments. This is because there is no obedience of anyone in things that displease Allah. However, in doing so full respect of the parents has to be maintained. There should be no anger, rudeness or harsh language used. This is also an Islamic injunction. The fine balance between the practices of Deen has to be maintained in order to gain pleasure of Allah.
