My father does not perform the prayers, although he fully knows the teachings of Islam. Being his daughter, I cannot find the proper way to advise him. Also, when he prays he only does this to boast before people. What is the proper way to advise him?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.

We previously mentioned the ruling on a person who does not pray in Fatwa 85264, so kindly refer to it.

As for the ideal way to advise one's father, it is as follows:

1-   Dutifulness, obedience and kindness to your father will bring you closer to his heart, so that your advice will have a far-reaching effect.

2-   Choosing the right situations and incidents when he may be more responsive, such as death of a relative, an accident or the like.

3-   Seeking the help of those who are more likely to affect him, such a close friend, the Imaam of the mosque or any outspoken person who has a good approach when admonishing people.

4-   Avoiding embarrassing him, hurting his feelings or provoking him.

5-   Supplicating Allaah for him sincerely and earnestly, for Allaah The Almighty is The One to guide him.

Allaah Knows best.
