Claim: Thanksgiving is a secular/non religious holiday, and therefore there is no problem in celebrating it.
Response: Observance if an inherently christian american ritual is imitation of the Kuffar, which is sternly warned against.
Evidence: “Whoever imitates a people is one of them.” Narrated by Abu Dawood (4031) and classed as saheeh by al-Albaani in Saheeh Sunan Abi Dawood.
Claim: We are giving thanks to our creator, Allah, and strengthening family ties which are both required in Islam.
Response: This practice was not made ritual by the Prophet salallahu alai hi wasalaam or his sahaba, and is therefore Bida’ah.
Evidence: The Prophet (peace and blessings of Allaah be upon him) stated repeatedly that: “Every newly-invented thing is a bid’ah (innovation), every bid’ah is a going astray, and every going astray will be in the Fire.” (Reported by al-Nisaa’i in al-Sunan, Salaat al-‘Eedayn, Baab kayfa al-Khutbah).
Bida’h is defined as: any invented way in religion that is aimed at worshipping or drawing closer to Allaah. This means anything that is not referred to specifically in Sharee’ah, and for which there is no evidence (daleel) in the Qur’aan or Sunnah, and which was not known at the time of the Prophet (peace and blessings of Allaah be upon him) and his Companions.
