Question:

Assalamu Alaykum Wa RahmatUllahi Wa Barakatahu, Hazrat, My question is
Is it must to pray Fajr, Maghrib and Isha Prayers Loudly even when praying alone?

I am working in saudi arab and most of the time since i be in office i pray alone but i pray quietly because if i pray loudly some people just joins the salah and makes me Imam. I don't know whether its valid or not so i usually pray salah quietly.

Please suggest me which is the correct way of praying Fajr, Maghrib and Isha salah while praying alone.
Thank You.

Assalamu Alaykum Wa RahmatUllahi Wa Barakatahu.

Answer:

Wa alaykumussalam,

When praying Fajr, Maghrib and Isha on time (ada) alone, an individual has the option of reciting the Qur’an loudly or quietly. Although for Fajr, Maghrib and Isha it is preferred for a person praying salah alone to recite loudly, it is not necessary [Bahar e Shari'ah with reference to al-Durr al-Mukhtar]. 

Therefore, if you recite the Qur’an quietly (provided you can hear yourself if there is no disruption) in Fajr, Maghrib and Isha whilst praying alone, the salah is valid.
