Does the fact that prayer does not prevent indecency and evil mean that the prayer is not accepted?

To achieve the prayer that prevents indecency and evil, we recommend consistently performing prayer well, asking Allah for protection from sins, and persisting in supplication. You will find what pleases you, for "Indeed, so-and-so prays at night, but when morning comes, he steals." He (the Prophet) said: "What you say will surely restrain him."
