Kindness to Parents is a very enlightening booklet by Abdul Malik Al-Qasim. He has collected several stories and narrations that demonstrate the Birr (being dutiful) and kindness to our righteous Salaf towards their parents' needs and necessities, in obedience to Allah's worship in sincerity. He refers from the Noble Qur'an that a man is never allowed to say 'Uff" (fie) if he smells a bad order coming from his parents or one of them.
The author has exposed shortcomings and errors of many among us who don not preserve the rights of their parents.
