‘Ubaid Allah ibn ‘Adi ibn Khiyar related that he went in to see ‘Uthman ibn ‘Affan (may Allah be pleased with him) when he was being beseiged, and said: Indeed you are a leader [imam] of the people, and what you see has come upon you; we are being led in prayer by an imam of enticement, and we are in an uncomfortable situation. And he said: Prayer is the best thing that people can do, so whenever people do good, do good with them, and when they do wrong, stay away from their wrongdoing. Al-Zubaidi said that Al-Zuhri said: In our opinion one should not pray behind an effeminate man, except out of necessity if there is no other way.
