Sayyiduna Anas (may Allah be pleased with him) reports: It was asked from the Prophet (peace and blessings be upon him), "Who are the family of Muhammad (peace and blessings be upon him)?" He replied: "Every God-fearing person." Then he recited this verse: «إِنْ أَوْلِيَاؤُهُ إِلَّا الْمُتَّقُونَ» "Indeed, His friends are only the God-fearing." (Al-Anfal: 34)

Shahr bin Hawshab says: I came to Umm Salamah (may Allah be pleased with her) to offer condolences for Husayn bin Ali (may Allah be pleased with them both), so she said: Once the Prophet Muhammad (peace and blessings be upon him) came to me and sat on a sheet. Lady Fatimah (may Allah be pleased with her) brought something to him, and I placed it. The Prophet (peace and blessings be upon him) said: "Call Hasan, Husayn, and your cousin as well." When they had all gathered with him, the Prophet (peace and blessings be upon him) said about them: "These are my special children and my Ahl al-Bayt. O Allah! Remove impurity and filth from them, and purify them thoroughly."
