Is it permissible to cite weak hadiths as supporting evidence?

The student : Sometimes we find that the Shaykh al-Islam Ibn Taymiyyah and others cite some weak hadiths in some of their books. Is this permissible?

The Shaykh : We have what is valid. Perhaps in their vast memory, which has no limits, there may be some corroborating narrations that strengthen the content of the hadith in their view. Otherwise, this is a fault attributed to all authors who mention some hadiths that, when their chains of narration are examined, reveal their weakness. It is not permissible to mention them unless their weakness is clarified. However, they may have an excuse, as we mentioned, that there may be... there is something in the form of corroborating narrations that strengthens these hadiths they mentioned, without having clarified their weakness.
