Parent’s love for their children is pure, unconditional, and forgiving. It is impossible to reciprocate it fully. But we can ask for blessings of Almighty Allah upon them. Invocation for parents is necessary for their life as well as after death. Therefore their good deeds will not end with their death. But it will multiply along with each good deeds of children. Invocations from children are a continuous charity for them. It is also their right. Thus always keep praying for lovely parents.
