How should dua be made after the Fardh Salaat and Taraaweeh Salaat?

Answer

After the Fardh of Zuhr, Maghrib and Isha it is Sunnah to recite a very short dua individually and silently, not congregationally. After the Fardh of Fajr and Asr, everyone is at liberty to make his own dua for as long as he pleases.

After the 20 raka'ts of Taraaweeh, the dua should also be silently made. The Shariah does not stipulate how long this dua should be.
