Mashallah! I am very happy to read your post. You have indeed written very beautiful and loving things about your sister. You are right that there are certain people in life who have a profound influence on our thinking and emotions. Your sister is the person who is there like a light in your life. It is also clear from your writing that the hard work, dedication and love of your sister is a source of light not only for you but also for the people around you. You are lucky to have such sister in your life and learn from them every day. I pray that Allah always keeps your sister happy, healthy and successful and that the light of love and peace shines in both of your lives. Amen.
