It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "If I were to stone anyone without evidence, I would have stoned so-and-so (woman), from whose appearance, manner of speech and those who visit her suspicion (of indecency) has become evident."
