Allah s.w.t. says in the Quran:
Your Lord has decreed that you worship none but Him and that you be kind to parents. Whether one or both of them attain old age in your life, say not to them a word of contempt, nor repel them, but address them in terms of honour.
O Allah ! I am your slave. Our parents are a blessing for us. Keep them in goood health and forgive their sins and guide them and enter them into jannah. Making dua for our parents is great, but beyond that, we can also show our appreciation for them through other means that they can see and appreciate. Our parents have sacrificed so much to raise us. We can never repay them for their kindness. However, we can do our best to honor them and treat them well.
