Should we pray that our faith not fail?

I’ve heard you condemn the prayer ‘O Lord, help me to be pure, but not yet.’

Should we pray that our faith may not fail, but when restored we strengthen our brothers?

Luke 22:31-32 ESV
“Simon, Simon, behold, Satan demanded to have you, that he might sift you like wheat, [32] but I have prayed for you that your faith may not fail. And when you have turned again, strengthen your brothers.”
