p68.0 INGRATITUDE TO SOMEONE WHO DOES ONE A KINDNESS
p68.1 Allah Most High says:
“… to show thanks to Me, and to your parents … ” (Koran 31:14).
p68.2 The Prophet (Allah bless him and give him peace) said,
“He who does not thank people is unthankful to Allah.”
p68.3 One of the early Muslims said: “Ingratitude for a kindness is one of the enormities.
Gratitude consists of reciprocating it or supplicating for the person.”
