In this fatwa:
Weed of all types is haram in Islam, whether it is marijuana or any other type. Shariah forbids the consumption of drugs and intoxicants because of the great harm that they cause to the mind, soul, family and society.
Answering your question, the Fatwa Center at Islam Q and A, states:
Hashish of all types is haram, whether it is marijuana or any other type.
Ibn Hajar al-Haythami said in al-Fatawa al-Fiqhiyyah (4/233), speaking of hashish:
“The evidence for its being forbidden is the report narrated by Ahmad in his Musnad and by Abu Dawud in his Sunan with an authentic chain of transmitters from Umm Salamah (may Allah be pleased with him) who said: The Messenger of Allah (peace and blessings of Allah be upon him) forbade all kinds of intoxicants and relaxants.
The scholars said that relaxants are things that cause drowsiness and languor in the limbs. This hadith indicates that hashish in particular is haram, because it intoxicates and relaxes, which is why those who consume it sleep a great deal.
Al-Qarafi and Ibn Taymiyah narrated that there is scholarly consensus that it is haram and said: The one who regards it as permissible is an unbeliever. He said: The only reason why the four imams (may Allah have mercy on them) did not speak of it is that it was not known at their time, rather it only appeared at the end of the sixth century AH and the beginning of the seventh century when the Tatar state emerged.”
Shaykh al-Islam Ibn Taymiyah (may Allah have mercy on him) said in al-Fatawa al-Kubra (3/425):
“Consuming this hashih in solid form is haram, and it is one of the most evil of haram plants, whether a little of it is consumed or a lot.”
Consuming intoxicants is haram regardless of the way in which they are consumed.
Ibn Qasim al-Shafi`i said: “What is meant by the drinker is the consumer, whether it is drunk or consumed otherwise, whether there is consensus on its being forbidden or there is a difference of opinion concerning that, and whether it is solid or liquid, cooked or raw.”
Shariah only forbids the consumption of drugs and intoxicants because of the great harm that they cause to the mind, soul, family and society.
