Imam Ali (a.s.) said:
"إِتَّعِظُوا بِمَنْ كانَ قَبْلَكُمْ قَبْلَ أَنْ يَتَّعِظَ بِكُمْ مِنْ بَعْدَكُمْ"
Take counsel from your predecessors before the posterity takes counsel from your life and destiny.1
History is full of lessons, full of examples and advice . The consequences of injustice, oppression, stagnation and neglect of the needs of changing environment and times are all reflected in the mirror of history. Imam ‘Ali., with his extensive knowledge of human history, warns us to take counsel and learn lessons from the actions and mistakes and fate of our predecessors rather than repeat the same mistakes and leave a trail of misfortunes for the posterity to learn from.
