Musannaf Ibn Abi Shaybah 36000 — The affair of al-Qadisiyyah

Qays said: During the Battle of al-Qadisiyyah, an ulcer appeared on the foot of Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him), and he could not go out to fight. A retreat broke out among the people. The wife of Sayyiduna Sa'd, who had previously been married to Sayyiduna al-Muthanna bin Harithah al-Shaybani (may Allah be pleased with him), said: "There is no Muthanna for the horsemen!" At this Sayyiduna Sa'd slapped her. She said: "Out of cowardice and jealousy!" The narrator said: Then we defeated the enemy.
