Musannaf Ibn Abi Shaybah 5477 — Those who prayed two rakahs after

Humayd bin Hilal said: Sayyiduna Imran bin Husayn (may Allah be pleased with him) used to pray two rak'ahs after the Jumu'ah. Someone said to him: O Abu Nujayd! Have you heard what people are saying? He asked: What are people saying? The one informing him said: People say that Imran prays two rak'ahs so that four rak'ahs are completed! Imran said: That spears should strike my chest again and again is dearer to me than doing what people are saying about me. Then, on the following Friday, he prayed the Jumu'ah, then sat in ihtiba' (with his knees drawn up and wrapped), and he did not pray any prayer until the Asr prayer.
