Which Prayers' Qadaa Is Essential?Islamic Fiqh

                       Which prayers' Qadaa is essential?

Qadaa is "Waajib" (essential) of all those prayers which were missed, omitted i.e.not offered

during the prescribed time intentionally or unintentionally, few or many. 

However, one is not guilty if prayer is missed, omitted by sleep or forgetfulness but on waking up he should offer it immediately if it is not odious time. Further delay is Makrooh.
