neglecting to teach

"The one who neglects to teach his son that which will benefit him and leaves him to his own devices has wronged him severely.

Most children only become corrupt because of their parents and their neglect of them, and their failure to teach them the obligatory duties and Sunnahs of Islaam.

They neglect them when they are young then they are not able to benefit themselves or their parents when they grow up."

Ibn al-Qayyim (may Allaah have mercy on him) [Tuhfat al-Mawdood (p. 229)]
