Musannaf Ibn Abi Shaybah

Hazrat Amr bin Murrah (may Allah have mercy on him) narrates that Hazrat Abu Al-Bakhtari (may Allah have mercy on him) said: People asked Hazrat Ali (may Allah be pleased with him): "Tell us about yourself." He (may Allah be pleased with him) replied: "Whenever I used to ask something, it was granted to me. And when I remained silent, the conversation would be started with me."
