Mukhtasar Muslim

Narrated from Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) that a man sought permission to enter upon the Prophet (peace and blessings of Allah be upon him), so the Messenger of Allah (peace and blessings of Allah be upon him) said: "Give him permission, he is a bad person among his people." When he entered, the Messenger of Allah (peace and blessings of Allah be upon him) spoke to him gently. Umm al-Mu'mineen Aisha Siddiqa (may Allah be pleased with her) said: "O Messenger of Allah! You said such about him, then you spoke to him gently." So he (peace and blessings of Allah be upon him) said: "O Aisha! The worst person in the sight of Allah on the Day of Resurrection will be the one whom people avoid because of his evil."
