“Why did you not argue against them (anṣār) that the Prophet had left his will that whoever is good among anṣār should be treated well and whoever is bad he should be forgiven.” People said : “What is there against them in it?” Amīr al-mu’minīn said : “If the Government was for them there should have been no will in their favour.” Then he said : “What did the Quraysh plead?” People said : “They argued that they belong to the lineal tree of the Prophet.” Then Amīr al-mu’minīn said : “They argued with the tree but spoiled the fruits.”
