Concise Quran Commentary
Your Lord - O servant - has instructed and made obligatory that you worship none but Him, and He has instructed that you be good to your parents, especially when they become old. If either of them or both of them reach old age with you, do not become annoyed with them by uttering words that indicate the same, do not scold them and do not be harsh when speaking to them, but say to them kind words that are soft and courteous.
