By assassinating Imam Ali (a.
By assassinating Imam Ali (a.s.), they actually aimed at assassinating the message, the history, the culture and the nation of Muslims embodied in the person of Imam Ali bin Abi Talib (a.s.). In doing so, the Islamic nation lost its guide of progress, and at the most wonderous opportunity in its life after the Messenger of Allah (s.a.w.).
Imam Ali (a.s.) suffered from his wound for three days, during which he entrusted his son, Imam Hasan (a.s.) with the Imamate of guiding the nation ideologically and socially. During those three days, as during all his life, he never ceased remembering Allah, praising Him, and accepting Him and His ordinance.
Likewise, he continued giving pieces of advice and directions leading to good, pointing to the right, defining the way to guidance, explaining the course for deliverance, calling for the observance of Allah's ordinances, and warning against following one's ill desires and set-backs from not carrying our the divine message.
The following is one piece of advice offered to his sons, Imams Hasan and Hussain (a.s.), as well as to his people, the nation and coming generations: "I advise you to fear Allah, and not to run after (the pleasure of) the world, even if it may run after you. Do not be sorry for anything from it which you have been denied. Say the truth and act for(Allah's) reward. Be an enemy of the oppressor, and be a helper of the oppressed.
"I advise you, my children, my household and all those who may receive my message, to fear Allah, to arrange your affairs well, to maintain good relations among yourselves, for I have heard your grandfather (s.a.w.) saying: 'Good relations are better than prayer and fasting in general.' "(Fear) Allah when handling matters of orphans. Do not let them starve, nor allow them to be lost as long as you are there.
"(Fear) Allah in respect to your neighbors, for they were the truest of your Prophet (s.a.w.). He went on asking us to take care of them, so much that we thought he would make them heirs (of our heritage). "(Fear) Allah in respect to the Qur'an, (take care that) no one may excel you in following its tenets. "(Fear) Allah in respect to prayer, as it is the pillar of your religion.
"(Fear) Allah in respect to your Lord's House (Ka'bahh), do not forsake it so long as you live, because if you do you will not be looked upon with respect. "(Fear) Allah in respect to jihad, fight with your wealth, your lives and your tongues, in the way of Allah.
