Reciting aloud in nafl salaah
Q:
1. Regarding any nafl salaah, I would like to know if it is permissible to read the qiraat aloud, for purposes of dhor?
2. If it is, should one perform the salaah as though leading a jamaat, i.e. say takbeer for postures aloud, etc.
3. Do the same rules above apply for qadha salaah as well?
4. What are the rules for performing nafl salaah in jamaat, e.g. with one's spouse or household?
