In addition to obedience to parents, one of the moral lessons in Q.17:23 is perseverance. The verse states, "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 honor." This verse highlights the importance of showing respect and kindness towards parents, even in difficult situations. Perseverance is necessary because it can be challenging to remain patient and respectful towards parents, especially when they are old and in need of constant care. The verse encourages us to persevere and continue to treat our parents with kindness, regardless of the difficulties we may face.
