Cremation is not allowed in Islam. Cremation is something contrary to the teachings of Islam and is a violation of Islamic Law.
Allah says: “Then He causes him to die, and places him in his grave” [Sûrah `Abasa: 21]
The Prophet (peace be upon him) said: “The way of honoring the deceased is to bury him”.
It is an obligation on the Muslims as a community to ensure that every Muslim who dies is properly washed, shrouded, and buried. The funeral prayer of the deceased should be performed after the body of the deceased is shrouded and before the deceased is taken to the grave.
This is one of the rights that an individual Muslim has on the Muslim community.
And Allah knows best.
