Is Ishraaq or Chasht (or Dhuha) two separate kind of optional prayers?
Extra prayers after sunset till before the Zuhr time enters. Majority Fuqaha / Ulama say that the two prayers are one and the same – called Ishraaq when prayed early on and Dhuhaa when prayed later on.
As per Sufiyya – two distinct prayers. Ishraaq (2 to 4 raka’ts). Duhua (Chasht) (8 to 12 raka’ts)
