Q 3: I heard someone saying:
The Prophet (peace be upon him) said: "Learn Sihr (witchcraft), but do not practice it." Is this a Hadith Sahih (a Hadith that has been transmitted by people known for their uprightness and exactitude; free from eccentricity and blemish)?
To the best of my knowledge, this is a Hadith Mawdu` (fabricated Hadith) that has not been reported from the Prophet (peace be upon him).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
