Answered by Shaykh Faraz Rabbani
When I pray alone can I pray Fajr, Magrib, and Isha silently or does it have to be aloud?
Walaikum assalam wa rahmatullah,
When praying the loud prayers alone, it is permitted to recite them quietly or aloud, though the latter is superior for men. [Shurunbulali, Maraqi al-Falah; Haskafi , Durr al-Mukhtar]
