MUHAMMAD’S TEACHINGS TO MANKIND
“ The Messenger of God, peace and blessings of God be upon him, said, "Among the grave sins is the insult of one’s parents." They exclaimed, "Messenger of God, does a man (1) insult his parents?" He replied, "Yes. He curses a man's (1) father, so he insults his father; and he insults the man's mother so he curses his mother." Footnotes: (1) Masculine pronouns are generally used in Arabic as a means for referring to both men and women when the meaning is left general and is not otherwise specified. ”
