Saying "Ameen" is permissible after reciting the Surah of al-Hamd in the Salat (but it's still not part of the Salat) especially with the intention of supplication.
Mohammad Hussein FadlallahWhat is meant here is that man should not become immersed in loving the world which will make him forget the responsibilities that Allah had ordered him to hold, but he has to look at the world in its reality, in which it represents a place for obeying Allah.
Mohammad Hussein FadlallahThroughout my life, I have always supported the human being in his humanism and I have supported the oppressed. I think it is the person's right to live his freedom and it is her and his right to face the injustice imposed on each by revolting against it, using his practical, realistic and available means to end the oppressor's injustice toward him, whether it is an individual, a community, a nation, or a state; whether male or female.
