Are the two rak'ahs after 'Isha considered among the regular sunnah prayers (rawatib), and should they be prayed immediately after it, or is it permissible to delay them until after the Qiyam (night prayer)? Also, regarding the regular sunnah prayer before Dhuhr, is it permissible to pray it before the Adhan, and what is the permissible duration for that?
It is sunnah to pray two rak'ahs of regular supererogatory prayer after the 'Isha prayer. Its time begins with the entry of the 'Isha prayer time and ends at midnight. It is best to pray it immediately after 'Isha, and it is permissible to delay it until midnight, but it is not permissible to delay it past midnight except for a valid excuse.
