Machine translationRead the Arabic original
Question: What is the ruling on one who performs Hajj while abandoning prayer, whether intentionally or out of negligence? Does it count as the Hajj of Islam?
Answer: If one performs Hajj while abandoning prayer, and if he does so by denying its obligation, he is a disbeliever by scholarly consensus, and his Hajj is not valid. As for if he abandons it out of laxity and negligence, there is disagreement among the scholars on this; some hold that his Hajj is valid, while others do not hold it to be valid. The correct view is that his Hajj is not valid either; based on the saying of the Prophet (peace and blessings be upon him):Sunan Ibn Majah 1079Sahih (Darussalam), and his saying (peace and blessings be upon him): Sahih Muslim 82b. This encompasses the one who denies its obligation and the one who abandons it out of negligence. And success is from Allah.

The covenant that distinguishes between us and them is prayer; so whoever leaves it, he has committed Kufr.
العهد الذي بيننا وبينهم الصلاة فمن تركها فقد كفرBetween man and polytheism and unbelief is the abandonment of salat.
بين الرجل وبين الشرك والكفر ترك الصلاة
