Arabic (Original)
حَدَّثَنَا وَكِيعٌ عَنْ سُفْيَانَ عَمَّنْ سَمِعَ أَنَسًا يَقُولُ مَرَّ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِسَعْدٍ وَهُوَ يَدْعُو بِأُصْبُعَيْنِ فَقَالَ أَحِّدْ يَا سَعْدُ.
English Translation
Waki' told us, from Sufyan, from someone who heard Anas say: The Messenger of God, peace and blessings be upon him, passed by Sa'd while he was supplicating with two fingers raised, and said, "Make it one, O Sa'd."
