Performing Hajj after making Tawbah from Bid`ahs

Q 1: In India, we practice acts which are considered Bid`ah (innovation in Islam) and Shirk (associating others with Allah in His Divinity or worship) such as preparing and dedicating food to Imam Ja`far Al-Sadiq, and celebrating the eleventh day. When we traveled to the Kingdom of Saudi Arabia we performed Hajj. Is this Hajj valid?

A: Whoever commits acts of major Shirk (associating others with Allah in His Divinity or worship) such as beseeching the dead and vowing in their name then performs sincere Tawbah (repentance to Allah) from these acts and abandons them, their Hajj performed after Tawbah is valid. On the other hand, if Hajj is performed without offering Tawbah from these acts of Shirk, the Hajj as well as any good deeds are invalidated. Allah (Exalted be He) states: But if they had joined in worship others with Allâh, all that they used to do would have been of no benefit to them. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
