Is a weak hadith acted upon if its meaning is correct?

Question:
A hadith may have a weak chain of narration, but its meaning is correct. Is it acted upon?

Answer:
The original principle is acted upon. The original principle is what is indicated by the Qur'an and authentic hadiths.
Q: Shaykh Nasir al-Albani (may Allah preserve him) says that a weak hadith is based on conjecture, and for this reason he does not see it as being acted upon; because it is based on conjecture, and conjecture is the most false of speech?
The Shaykh: No, no. Weak hadiths are used in encouraging good and warning against evil, and they are used in matters where their original principle is established.
Q: In response to this, he said that authentic hadiths are full of hadiths of encouragement and warning, so why are they dispensed with?
The Shaykh: There is no harm. Mentioning them is in the category of encouraging good and warning against evil. It is narrated from the Prophet (peace and blessings be upon him), just as the scholars said. It is narrated without asserting certainty.
