23. al-Manāqib –quoting from Sa`id ibn al-Musayyib: Ali (a.s.) left and went back home. People rushed towards him and the companions of the Messenger of God (s.a.w.) were saying: “Ali is the Commander of the Faithful”, until they entered his house and said: “We swear allegiance to you, so extend your hand because there is no other choice but to have a commander.”
At this moment Ali (a.s.) said: “This is not up to you. It is the right of the people of Badr. Whomever the people of Badr agree upon will be appointed as the caliph.” All of the people of Badr came to Ali (a.s.) and said: “We do not know anyone more rightful for it than you. Hold out your hand to us to swear allegiance to you.
Then Ali (a.s.) said: “Where are Talha and Zubair?” The first one who swore allegiance was Talha who did so by shaking his hand, and his [Talha’s] fingers were limping then Ali (a.s.) took it as a bad omen, saying: “How befitting is it for it [caliphate] to be broken!” After that, Zubair, Sa`d and other companions of the Prophet (s.a.w.) swore their allegiance to him.¹

23. المناقب للخوارزمي عن سعيد بن المُسَيَّب: خَرَجَ عَلِيٌّ علیه السلام فَأَتى مَنزِلَهُ، وجاءَ النّاسُ كُلُّهُم يُهرَعونَ¹ إلى عَليٍّ، وأصحابُ رَسولِ اللهِ صلی الله علیه وآله يَقولونَ: أميرُ المُؤمِنينَ عَلِيٌّ، حَتّى دَخَلوا عَلَيهِ دارَهُ، فَقالوا لَهُ: نُبايِعُكَ، فَمُدَّ يَدَكَ؛ فَلابُدَّ مِن أميرٍ.
فَقالَ عَلِيٌّ: لَيسَ ذلِكَ إلَيكُم، إنَّما ذلِكَ لاَِهلِ بَدر، فَمَن رَضِيَ بِهِ أهلُ بَدرٍ فَهُوَ خلَيفَةٌ. فَلَم يَبقَ مِن أهلِ بَدرٍ إلّا أتى عَلِيّاً، فَقالوا: ما نَرَى أحَداً أحَقَّ بِها مِنكَ؛ مُدَّ يَدَكَ نُبايِعكَ. فَقالَ: أينَ طَلحَةُ وَالزُّبَيرُ؟ فَكانَ أوَّلُ مَن بايَعَهُ طَلحَةَ، فَبايَعَهُ بِيَدِهِ، وكانَت إصبَعُ طَلحَةَ شَلّاءَ، فَتَطَيَّرَ مِنها عَلِيٌّ وقالَ: ما أخلَقَهُ أن يُنكَثَ. ثُمَّ بايَعَهُ الزُّبَيرُ، وسَعدٌ، وأصحابُ النَّبِيِّ صلی الله علیه وآله جَميعاً.²
