Musannaf Ibn Abi Shaybah 37523 — The words of al-Dahhak bin Qays

It is narrated from al-Majishun bin Abi Salamah that he said: Sayyiduna Sa'd bin Mu'adh (may Allah be pleased with him) said: Apart from three things, I am still weak. I never heard anything from the Prophet (peace and blessings be upon him) except that I knew it to be true. I never prayed any prayer during which anything distracted me from it until I finished the prayer. And I never followed a funeral with anything in my heart other than what it is saying or what is being said to it, until we finished with it.
