Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: “Just as we owe duties of kindness towards them during their life, we do owe them a debt of gratitude after death. The Prophet (peace and blessings be upon him) was once asked, “Do I owe anything towards my parents after their death?” He replied, “You owe it to them to pray for them and ask forgiveness of Allah; to fulfill their promises after them; foster their ties of kinship and to honor their friends.”
According to many scholars, the following deeds can also be done on behalf of our parents: offering charities, performing pilgrimages, fasting, and reading the Qur’an and making supplications.
So go ahead and do the good works you can afford to do for the benefit of the soul of your mother. May Allah make us all loyal to our parents by cherishing their memory and doing what we can to benefit their souls. Ameen.”
