[Machine] I said to Al-Hasan ibn Ali that people are saying you want the caliphate. He replied, "The leaders of the Arabs were in my hands; they would fight whoever I fought and make peace with whoever I made peace with. I abandoned it seeking the pleasure of Allah Almighty and to spare the blood of the nation of Muhammad ﷺ . Then it was taken from me by the deceit of the people of Hijaz."

This is a sound chain of narration according to the criteria of the two Sheikhs (al-Bukhari and Muslim), but they did not include it.  

قُلْتُ لِلْحَسَنِ بْنِ عَلِيٍّ إِنَّ النَّاسَ يَقُولُونَ إِنَّكَ تُرِيدُ الْخِلَافَةَ فَقَالَ «قَدْ كَانَ جَمَاجِمُ الْعَرَبِ فِي يَدِي يُحَارِبُونَ مَنْ حَارَبْتُ وَيُسَالِمُونَ مَنْ سَالَمْتُ تَرَكْتُهَا ابْتِغَاءَ وَجْهِ اللَّهِ تَعَالَى وَحَقْنَ دِمَاءِ أُمَّةِ مُحَمَّدٍ ﷺ ثُمَّ ابْتَزَّهَا بِاتِّئَاسِ أَهْلِ الْحِجَازِ»
