Sunan Abi Dawud 25136
In-book no 4632حَدَّثَنَا مُحَمَّدُ بْنُ مِسْكِينٍ، حَدَّثَنَا مُحَمَّدٌ، - يَعْنِي الْفِرْيَابِيَّ - قَالَ سَمِعْتُ سُفْيَانَ، يَقُولُ مَنْ زَعَمَ أَنَّ عَلِيًّا، عَلَيْهِ السَّلاَمُ كَانَ أَحَقَّ بِالْوِلاَيَةِ مِنْهُمَا فَقَدْ خَطَّأَ أَبَا بَكْرٍ وَعُمَرَ وَالْمُهَاجِرِينَ وَالأَنْصَارَ وَمَا أُرَاهُ يَرْتَفِعُ لَهُ مَعَ هَذَا عَمَلٌ إِلَى السَّمَاءِ .
Muhammad al-Firyabl said: I heard Sufyan say: If anyone thinks that ‘All (Allah be pleased with him) was more deserving for the Caliphate than both of them, he imputed error to Abu Bakr, ‘Umar, the Muhajirun (Immigrants), and the Ansar (Helpers) Allah be pleased with all of them. I think that with this (belief) none of his action will rise to the heaven.
