Why Do We Recite Aloud In Some Prayers While We Do It In A Low Voice In Some Others?

What should be done about the mosques which were built toward the wrong direction?

Worships are tawqifi, which means it is not possible to know their reasons to be fardh and their practices with logic. They are preformed as commanded by Allah and in the way performed by Prophet Muhammad (saw). This applies to prayer as well. The Prophet (saw) said, “Pray as you have seen me praying.” (Bukhari, Adhan, 18)

Likewise, the practices of reciting silently in fardh prayers established in daytime and aloud in fardh prayers established at night are based on Prophet Muhammad’s (saw) sunnah and the practices of his Companions who learned the religion directly from him and taught it to the following generations (See. Bukhari, Salat, 96-105; Abu Dawud, Salat, 131, 134, 137).
