What are the etiquettes of the mosque, especially between the Adhan and Iqamah, concerning those in the first row, facing away from the Qiblah and extending one's legs, raising one's voice, discussing, exchanging conversations, and reciting the Quran?

Raising one's voice in the mosque contradicts the etiquette of mosques and the reverence and respect due to them, making them resemble marketplaces. As for facing away from the Qiblah and extending one's legs, there is no harm in it unless it is considered reprehensible by custom; otherwise, it is a breach of chivalry and should be avoided in mosques.
