أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ أَبِي بُرْدَةَ، قَالَ قَالَ عَلِيٌّ قَالَ لِي رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يَا عَلِيُّ سَلِ اللَّهَ الْهُدَى وَالسَّدَادَ ‏"‏ ‏.‏ وَنَهَانِي أَنْ أَجْعَلَ الْخَاتَمَ فِي هَذِهِ وَهَذِهِ ‏.‏ وَأَشَارَ يَعْنِي بِالسَّبَّابَةِ وَالْوُسْطَى ‏.‏
Translation
It was narrated that 'Ali said

"The Messenger of Allah [SAW] said to me: 'Say: O Allah, guide me and make me steadfast,' and he forbade me to put a ring on this one and this one" - and Bishr (one of the narrators) pointed to his forefinger and middle finger. And 'Asim said: "One of the two of them."
