Some translated verses from the Quran,
“Worship Allah and join none with Him in worship, and do good to parents” (Quran, 4:36).
“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.“ (Quran, 17:23)
“And We have enjoined on man (to be dutiful and good) to his parents. His mother bore him in weakness and hardship upon weakness and hardship, and his weaning is in two years give thanks to Me and to your parents, unto Me is the final destination.” (Quran 31:14)
