It is narrated from Hazrat Anas (may Allah be pleased with him) that he says: I went to Hazrat Abu Ubaidah bin Jarrah (may Allah be pleased with him), so he accommodated me at one side of his house, while his wife was at another side. And there was a curtain between us. Then he would milk the she-camel and bring the vessel, then place it in my hand. Upon this, a man from among the Tulaqa said to him: Do you accommodate this man in your house with your wife? So he replied: I consider this man to be completely chaste.
