Arif billah Dr. Abdul HayyArifi (Allah have mercy on him) wrote in his will,
“Obedience to parents is a magnanimous investment for a blessed fortune.
Following faith in and practice of Islam, having love and fulfilling the rights of Allah and His beloved Prophet (may Allah’s blessing and peace be on him) the most important obligation is the fulfillment of the rights of parents.
It is essential (wajib) to keep them content and acquire their approval by providing assistance (kidhmat) to them in their lifetime.
And (it is also essential that) after their death, one makes supplications of forgiveness (magfirah) and passes on the reward of good deeds to them (esale thawab).”
