Didn't he swear me his allegiance after ...

Amir al-Mu’minin said about Marwan ibn al-Hakam at Basrah. When Marwan was taken on the day of Jamal, he asked Hasan and Husayn (p.b.u.t.) to intercede on his behalf before Amir al-Mu’minin. So they spoke to Amir al-Mu’minin about him and he released him. Then they said, "O' Amir al-Mu’minin he desires to swear you allegiance" Whereupon Amir al-Mu’minin said: Did he not swear me allegiance after the killing of ‘Uthman? Now I do not need his allegiance, because his is the hand of a Jew. If he swears me allegiance with his hand he would violate it after a short while. Well, he is to get power for so long as a dog licks his nose. He is the father of four rams (who will also rule). The people will face days through him and his sons.1

ومن كلام له (عليه السلام) قاله لمروان بن الحكم بالبصرة قالوا: أُخِذَ مروان بن الحكم أَسيراً يوم الجمل، فاستشفع الحسن والحسين (عليهما السلام) إلى أَميرالمؤمنين (عليه السلام)، فكلّماه فيه، فخلّى سبيله، فقالا له: يبايعك يا أميرالمؤمنين؟ فقال: أَفَلَمْ يُبَايِعْنِي بَعْدَ قَتْلِ عُثْمانَ؟ لاَ حَاجَةَ لِي في بَيْعَتِهِ! إِنِّهَا كَفٌّ يَهُودِيَّةٌ لَوْ بَايَعَنِي بِيَدِهِ لَغَدَرَ بِسُبَّتِهِ. أَمَا إِنَّ لَهُ إِمْرَةً كَلَعْقَةِ الْكَلْبِ أَنْفَهُ، وَهُوَ أَبُو الاْكُبُشِ الاْرْبَعَةِ، وَسَتَلْقَى الاْمَّة مِنْهُ وَمِنْ وَلَدِهِ يَوْمَاً أَحْمَرَ!
