Parents in our lives play a significant role, especially the father. The inner pain can not explained or represented through words. Apu I can relate to your pain because I have also lost my father, I didn’t lose a guardian but literally lost a best friend in my childhood to whom I can express every detail of my life. Yes your prayers and your good deeds for him will rest his soul. The way you feed the needy is really appreciated. In every family get-together or occasion, you and your family will feel his emptiness this is the rash reality of life. No one can replace his place in this world. I love the way how have taken responsibility to make sure about everyone's comfort. May Allah grant Uncle in Jannatul Ferdous and also make you along with your family more stronger to bear this grief.
