Muhammad bin Ali said to Sayyiduna Ibn Abbas (may Allah be pleased with them): "Do you remember when both of us were to the right and left of Sayyiduna Ali (may Allah be pleased with him), and he, upon hearing the curse upon the killers of Uthman from Sayyidatuna Aisha (may Allah be pleased with her), said: I too curse the killers of Uthman in the open and in the mountains." Ibn Abbas (may Allah be pleased with them) said: "Yes." Muhammad said: "Are we both not trustworthy?"
