Exhorting people for jihad
ومن خطبة له (عليه السلام)
وقد قالها يستنهض بها الناس حين ورد خبر غزوالانبار بجيش معاوية فلم ينهضوا، وفيها يذكر فضل الجهاد، ويستنهض الناس، ويذكر علمه بالحرب، ويلقي عليهم التبعة لعدم طاعته
Indeed, surely jihad is one of the doors of Paradise, which Allah has opened for His chief friends. It is the dress of piety and the protective armour of Allah and His trustworthy shield. Whoever abandons it Allah covers him with the dress of disgrace and the clothes of distress. He is kicked with contempt and scorn, and his heart is veiled with screens (of neglect). Truth is taken away from him because of missing jihad. He has to suffer ignominy and justice is denied to him.

امَّا بَعْدُ، فَإِنَّ الجِهَادَ بَابٌ مِنْ أَبْوَابِ الجَنَّةِ، فَتَحَهُ اللهُ لِخَاصَّةِ أَوْلِيَائِهِ، وَهُوَ لِباسُ التَّقْوَى، وَدِرْعُ اللهِ الحَصِينَةُ، وَجُنَّتُهُ الوَثِيقَةُ، فَمَنْ تَرَكَهُ رَغْبَةً عَنْهُ أَلبَسَهُ اللهُ ثَوْبَ الذُّلِّ، وَشَمِلَهُ البَلاَءُ، وَدُيِّثَ بِالصَّغَارِ وَالقَمَاءَةِ وَضُرِبَ عَلَى قَلْبِهِ بِالاْسْهَابِ وَأُدِيلَ الحَقُّ مِنْهُ بِتَضْيِيعِ الجِهَادِ، وَسِيمَ الخَسْفَـ، وَمُنِعَ النَّصَفَ
Beware! I called you (insistently) to fight these people night and day, secretly and openly and exhorted you to attack them before they attacked you, because by Allah, no people have been attacked in the hearts of their houses but they suffered disgrace; but you put it off to others and forsook it till destruction befell you and your cities were occupied. The horsemen of Banu Ghamid1 have reached al-Anbar and killed Hassan ibn Hassan al-Bakri. They have removed your horsemen from the garrison.

أَلاَ وَإِنِّي قَدْ دَعَوْتُكُمْ إِلَى قِتَالِ هؤُلاَءِ القَوْمِ لَيْلاً وَنَهَاراً، وَسِرّاً وَإِعْلاَناً، وَقُلْتُ لَكُمُ: اغْزُوهُمْ قَبْلَ أَنْ يَغْزُوكُمْ، فَوَاللهِ مَا غُزِيَ قَوْمٌ قَطُّ في عُقْرِ دَارِهِمْ إِلاَّ ذَلُّوا، فَتَوَاكَلْتُمْ وَتَخَاذَلتُمْ حَتَّى شُنَّتْ عَلَيْكُمُ الغَارَاتُ وَمُلِكَتْ عَلَيْكُمُ الاْوْطَانُ. وَهذَا أَخُو غَامِدٍ قَدْ وَرَدَتْ خَيْلُهُ الاْنْبَارَ وَقَدْ قَتَلَ حَسَّانَ بْنَ حَسَّانَ البَكْرِيَّ، وَأَزَالَ خَيْلَكُمْ عَنْ مَسَالِحِهَا
I have come to know that every one of them entered upon Muslim women and other women under protection of Islam and took away their ornaments from legs, arms, necks and ears and no woman could resist it except by pronouncing the verse,

“We are for Allah and to Him we shall return.” (2:156)

Then they got back laden with wealth without any wound or loss of life. If any Muslim dies of grief after all this he is not to be blamed but rather there is justification for him before me.

وَلَقَدْ بَلَغَنِي أَنَّ الرَّجُلَ مِنْهُمْ كَانَ يَدْخُلُ عَلَى المَرْأَةِ المُسْلِمَةِ، وَالاْخْرَى المُعَاهَدَةِ فيَنْتَزِعُ حِجْلَهَا وَقُلْبَهَا وَقَلاَئِدَهَا، وَرِعَاثَهَا ما تَمْتَنِعُ مِنْهُ إِلاَّ بِالاسْتِرْجَاعِ وَالاِسْتِرْحَامِ ثُمَّ انْصَرَفُوا وَافِرِينَ مَا نَالَ رَجُلاً مِنْهُمْ كَلْمٌ وَلاَ أُرِيقَ لَهُمْ دَمٌ، فَلَوْ أَنَّ امْرَأً مُسْلِماً مَاتَ مِن بَعْدِ هَذا أَسَفاً مَا كَانَ بِهِ مَلُوماً، بَلْ كَانَ بِهِ عِنْدِي جَدِيراً.
How strange! How strange! By Allah my heart sinks to see the unity of these people on their wrong and your dispersion from your right. Woe and grief befall you. You have become the target at which arrows are shot. You are being killed and you do not kill. You are being attacked but you do not attack. Allah is being disobeyed and you remain agreeable to it.

When I ask you to move against them in summer you say it is hot weather. Spare us till heat subsides from us. When I order you to march in winter you say it is severely cold; give us time till cold clears from us. These are just excuses for evading heat and cold because if you run away from heat and cold, you would be, by Allah, running away (in a greater degree) from sword (war).

فَيَا عَجَباً! عَجَباًـ وَاللهِ ـ يُمِيتُ القَلْبَ وَيَجْلِبُ الهَمَّ مِن اجْتِماعِ هؤُلاَءِ القَوْمِ عَلَى بَاطِلِهمْ، وَتَفَرُّقِكُمْ عَنْ حَقِّكُمْ! فَقُبْحاً لَكُمْ وَتَرَحاً حِينَ صِرْتُمْ غَرَضاً يُرمَى يُغَارُ عَلَيْكُمْ وَلاَ تُغِيرُونَ، وَتُغْزَوْنَ وَلاَ تَغْرُونَ، وَيُعْصَى اللهُ وَتَرْضَوْن! فَإِذَا أَمَرْتُكُمْ بِالسَّيْرِ إِلَيْهِم فِي أَيَّامِ الحَرِّ قُلْتُمْ: هذِهِ حَمَارَّةُ القَيْظِ أَمْهِلْنَا يُسَبَّخُ عَنَّا الحَرُّ وَإِذَا أَمَرْتُكُمْ بِالسَّيْرِ إِلَيْهِمْ فِي الشِّتَاءِ قُلْتُمْ: هذِهِ صَبَارَّةُ القُرِّ، أَمْهِلْنَا يَنْسَلِخْ عَنَّا البَرْدُ، كُلُّ هذا فِرَاراً مِنَ الحَرِّ وَالقُرِّ؛ فَإِذَا كُنْتُمْ مِنَ الحَرِّ وَالقُرِّ تَفِرُّونَ فَأَنْتُمْ وَاللهِ مِنَ السَّيْفِ أَفَرُّ!
O you semblance of men, not men, your intelligence is that of children and your wit is that of the occupants of the curtained canopies (women kept in seclusion from the outside world). I wish I had not seen you nor known you. By Allah, this acquaintance has brought about shame and resulted in repentance. May Allah fight you! You have filled my heart with pus and loaded my bosom with rage. You made me drink mouthful of grief one after the other.

You shattered my counsel by disobeying and leaving me so much so that Quraysh started saying that the son of Abi Talib is brave but does not know (tactics of) war. Allah bless them! Is any one of them fiercer in war and older in it than I am? I rose for it although yet within twenties, and here I am, have crossed over sixty, but one who is not obeyed can have no opinion.

يَا أَشْبَاهَ الرِّجَالِ وَلاَ رِجَالَ! حُلُومُ الاْطْفَالِ، وَعُقُولُ رَبّاتِ الحِجَالِ لَوَدِدْتُ أَنِّي لَمْ أَرَكُمْ وَلَمْ أَعْرِفْكمْ مَعْرِفَةً ـ وَاللهِ ـ جَرَّتْ نَدَماً، وَأَعقَبَتْسَدَماً قَاتَلَكُمُ اللهُ! لَقَدْ مَلاَتُمْ قَلْبِي قَيْحاً وَشَحَنْتُمْ صَدْرِي غَيْظاً، وَجَرَّعْتُمُونِي نُغَبَ التَّهْمَامِ أَنْفَاساً وَأَفْسَدْتُمْ عَلَيَّ رَأْيِي بِالعِصْيَانِ وَالخذْلاَن، حَتَّى قَالَتْ قُريْشٌ: إِنَّ ابْنَ أَبِي طَالِبٍ رَجُلٌ شُجَاعٌ، وَلْكِنْ لاَ عِلْمَ لَهُ بِالحَرْبِ. للهِ أَبُوهُمْ! وَهَلْ أَحدٌ مِنْهُمْ أَشَدُّ لَهَا مِرَاساً وَأَقْدَمُ فِيهَا مَقَاماً مِنِّي؟! لَقَدْ نَهَضْتُ فِيهَا وَمَا بَلَغْتُ العِشْرِينَ، وها أناذا قَدْ ذَرَّفْتُ عَلَى السِّتِّينَ! وَلكِنْ لا رَأْيَ لَمِنْ لاَ يُطَاعُ!
