Indeed, Islam orders us to be kind and loyal to parents. Referring to this, Allah Almighty says: (Thy Lord has decreed, that you worship none save Him, and (that you show) kindness to parents. If one of them or both of them attain old age with thee, say not ‘Fie’ unto them nor repulse them, but speak unto them a gracious word.) (Al-Isra’ 17: 23)
However, favouring parents and being dutiful to them is not allowed if such favoring and that obedience involve disobedience to Allah.
