Taharah in Shari'ah is observed in all the following forms except
Wudu
Tayammum
Istijabah
Ihraam
Correct answer is C
sa'at al istijabah (a time when du'a is answered).
All you have to do is make dua before Maghrib! Note: It's NOT 'Salat' (prayer), it's Sa'at (time) of istijabah (response). Sa'at al Istijabah is not a form of taharah (purification), but an important time to make du'a.
