Hajj on Behalf of Mother Who Never Prayed
Is it permissible for a daughter to perform Hajj and give in charity on behalf of her deceased mother, knowing that the mother did not pray during her life. What is the legal ruling in this, knowing that this daughter upholds that which is Islamically required of her from the pillars of Islam?
Whoever intentionally leaves off praying because he does not think it is obligatory, then he has committed Kufr according to the consensus of the Scholars. And whoever leaves off praying due to laziness and neglect, then he has also committed Kufr according to the majority of the two opinions of the Scholars, due to the saying of the Prophet (Peace and blessings be upon him):
"The covenant that is between us and them [the disbelievers] is the prayer. Whoever abandons it has committed Kufr" in addition to other evidences from the Qur'an and the Sunnah in this matter.
So based upon this, it is not permissible to perform Hajj nor to give in charity on behalf of anyone who has died and did not used to pray, just as one cannot perform Hajj nor give in charity on behalf of any of the Kuffar.
And with Allah lies all success and may Allah send prayers and salutations upon our Prophet (Peace and blessings be upon him) and his family and his companions.
