ومن كلام له (عليه السلام)
وقد استشاره عمر بن الخطاب
في الشخوص لقتال الفرس بنفسه
إِنَّ هذَا الاَْمْرَ لَمْ يَكُنْ نَصْرُهُ وَلاَ خِذْلاَنُهُ بِكَثْرَة وَلاَ بِقِلَّة، وَهُوَ دِينُ اللهِ الَّذِي أَظْهَرَهُ، وَجُنْدُهُ الَّذِي أَعَدَّهُ وَأَمَدَّهُ، حَتَّى بَلَغَ مَا بَلَغَ، وَطَلَعَ حَيْثُ طَلَعَ، وَنَحْنُ عَلَى مَوْعُود مِنَ اللهِ، وَاللهُ مُنْجِزٌ وَعْدَهُ، وَنَاصِرٌ جُنْدَهُ.
وَمَكَانُ الْقَيِّمِ بِالاَْمْرِ مَكَانُ النِّظَامِ مِنَ الْخَرَزِ يَجْمَعُهُ وَيَضُمُّهُ: فَإِنِ انْقَطَعَ النِّظَامُ تَفَرَّقَ وَذَهَبَ، ثُمَّ لَمْ يَجْتَمِعُ بِحَذَافِيرِهِ أَبَداً. وَالْعَرَبُ الْيَومَ وَإِنْ كَانُوا قَلِيلاً، فَهُمْ كَثِيرُونَ بَالاِْسْلاَمِ، عَزِيزُونَ بَالاجْتَِماعِ!
فَكُنْ قُطْباً، وَاسْتَدِرِ الرَّحَا بِالْعَرَبِ، وَأَصْلِهِمْ دُونَكَ نَارَ الْحَرْبِ، فَإِنَّكَ إِنْ شَخَصْتَ مِنْ هذِهِ الاَرْضِ انْتَقَضَتْ عَلَيْكَ الْعَرَبُ مِنْ أَطْرَافِهَا وَأَقْطَارِهَا، حَتَّى يَكُونَ مَا تَدَعُ وَرَاءَكَ مِنَ الْعَوْرَاتِ أَهَمَّ إِلَيْكَ مِمَّا بَيْنَ يَدَيْكَ.
إِنَّ الاَعَاجِمَ إِنْ يَنْظُرُوا إِلَيْكَ غَداً يَقُولُوا: هذا أَصْلُ الْعَرَبِ، فَإِذَا اقْتَطَعْتُمُوهُ اسْتَرَحْتُمْ، فَيْكُونُ ذلِكَ أَشَدَّ لِكَلَبِهِمْ عَلَيْكَ، وَطَمَعِهِمْ فِيكَ.
فَأَمَّا مَا ذَكَرْتَ مِنْ مَسِيرِ الْقَوْمِ إِلَى قِتَالِ المُسْلِمِينَ، فَإِنَّ اللهَ سُبْحَانَهُ هُوَ أَكْرَهُ لِمَسِيرِهِمْ مِنْكَ، وَهُوَ أَقْدَرُ عَلَى تَغْيِيرِ مَا يَكْرَهُ.
وَأَمَّا مَا ذَكَرْتَ مِنْ عَدَدِهِمْ، فَإِنَّا لَمْ نَكُنْ نُقَاتِلُ فِيَما مَضَى بِالْكَثْرَةِ، وَإِنَّمَا كُنَّا نُقَاتِلُ بِالنَّصْرِ وَالْمَعُونَةِ!
The fact is that there is no escape for men from a ruler good or bad. Faithful persons perform (good) acts in his rule while the unfaithful enjoys (worldly) benefits in it. During the rule, Allah will carry everything to its end. Through the ruler tax is collected, the enemy is fought, roads are protected and the right of the weak is taken from the strong till the virtuous enjoy peace and are allowed protection from (the oppression of) the wicked. (Sermon 40)The words which Amir al-mu'minin uttered in his advice are not indicative of any quality of Caliph `Umar except his being the ruler. There is no doubt that he held worldly authority, irrespective of the question of whether it was secured in the right way or wrong way. And where there is authority there is centring of people's affairs. That is why Amir al-mu'minin said that if `Umar would go out the Arabs would follow him in large numbers towards the battlefield, because when the ruler is on the march the people will not like to stay behind. The result of their going would be that city after city would become vacant, while the enemy will infer from their reaching the battlefield that the Islamic cities are lying vacant, and that if these people were repulsed no assistance would reach the Muslims from the centre. Again, if the ruler were killed the army would disperse automatically, because the ruler is as its foundation. When the foundation is shaken the walls cannot remain standing. The word "aslu'l-`Arab" (the root chief) of Arabia has not been used by Amir al-mu'minin as his own but he has taken it from the Persians. Obviously in his capacity as the head of the State, Caliph `Umar was, in their view, the chief of Arabia. Besides, the reference is to the country, not to Islam or Muslims, so that there is no suggestion of any importance for him from the Islamic point of view. When Amir al-mu'minin pointed out to Caliph `Umar that on his reaching there the Persians would aim at him, and that if he fell into their hands they would not spare him without killing, although such words would have touched the brave to the quick and would have heightened their spirits, `Umar liked the advice to stay back and thought it better to keep himself away from the flames of battle. If this advice had not been in accord with his personal inclination he would not have received it so heartily and would have tried to argue that the administration of the country could be maintained by leaving a deputy. Again when other people had already advised him to go out, what was the need for consulting Amir al-mu'minin except to get an excuse to stay back.
