How To Thank The Blessing
Do not associate anything with Allah and even if they burn or torment you as regards monotheism, endure it while you heart is sure of your faith; be kind to your parents both when they are living or dead and even if they asked you to give up your family and wealth, do so, for acceptance of this shows your faith.
Out of four persons of fighting in the battlefield, Miqdad said to the Holy Prophet, “My father is in the front against us: he has entered battle against you; would you give me permission to attack and kill him?” The Holy Prophet replied, “Let someone else do it, for if you kill your father in the way of Allah, your life will become short!”
Thanking the Blessing of Ahl al-Bayt
When the position of parents—be they Jews, Christians, Zoroastrians, or laic—is so high, how higher will be the position of Ahl al-Bayt who have a right of Imamate, loyalty and educational leadership on all human beings? They are Noah’s Ark in this world and the Hereafter and obedience to them will guarantee man’s happiness and prosperity.
To give Ahl al-Bayt’s their due right is to get to know them, to love them, to consider them as Noah’s Ark, and to obey their commands in all aspects of life. This is the way to offer our thanks for the blessing of Ahl al-Bayt.
