The Peak of Eloquence · Hadith 121 (#Passage #4)

ومنها : وَلَمْ يُبَايعْ حَتَّى شَرَطَ أَنْ يُؤْتِيَهِ عَلَى البَيْعَةِ ثَمَناً، فَلاَ ظَفِرَتْ يَدُ المبايِعِ، وخَزِيَتْ أَمَانَةُ المُبْتَاعِ فَخُذُوا لِلْحَرْبِ أُهْبَتَهَا وَأعِدُّوا لَهَا عُدَّتَهَا، فَقَدْ شَبَّ لَظَاهَا وَعَلاَ سَنَاهَا وَاسْتَشْعِرُوا الصَّبْرَ فَإِنَّهُ أحْزَمُ لِلنَّصْرِ.

Part of the same sermon on the settlement between Mu'āwiyah and ‘Amr ibn al-‘Āṣ : He did not swear allegiance till he got him agree that he would pay him its price. The hand of this purchaser (of allegiance) may not be successful and the contract of the seller may face disgrace. Now you should take up arms for war and arrange equipment for it. Its flames have grown high and its brightness has increased. Clothe yourself with patience for it is the best to victory. [1]
