I did wudoo’ for prayer, and during
the prayer I remembered that I had not rinsed my nose. What is the ruling concerning my
wudoo’ and my prayer in this case?

Praise be to Allaah.

Rinsing the nose in wudoo’ is obligatory, because it is proven
that the Prophet
(peace and blessings of Allaah be upon him) did this and said:
“Whoever does wudoo’, let him rinse his nose.” Whoever does not rinse his
nose, his wudoo’ is not valid. So you must repeat both your wudoo’ and your
prayer.
