Evidence from the authentic Sunnah.

The Shaykh : The Sunnah indicates the exaltation of Allah by speech, action, and affirmation. Are you with us, my man? ... Stand up, stand up, so you can pay attention. The Sunnah indicates this by speech, and what else? And by action and affirmation. Affirmation means the affirmation of others. As for speech, it is established from the Prophet (peace and blessings be upon him and his family) with certainty beyond doubt that he says in his prostration, what? affirming it and believing in it. Did I wake you up? Rest. As for action, listen, listen, my man. The greatest gathering of the Muslims with the Prophet (peace and blessings be upon him) was during the Farewell Pilgrimage. It was during the Farewell Pilgrimage. The Farewell Pilgrimage took place in the fourth year of the Hijrah, so I say. If I am mistaken, correct me. The Farewell Pilgrimage took place in the fourth year of the Hijrah. Wrong. May Allah reward you with good. Guide us, in which year?
The student: ...

The Shaykh : In the tenth year. In the tenth year of the Hijrah. At 'Arafah, when the Prophet (peace and blessings be upon him) delivered the great sermon, he established the foundations of Islam in it. He said: Look, look at his hand. O Allah, where did it go? Above. Bear witness. Below, where are those who are being witnessed against? On the earth. This is an indication of the exaltation of Allah by what? By speech or by action?
The student: By action.

The Shaykh : By action. Good. As for affirmation, this is Mu'awiyah ibn al-Hakam (may Allah be pleased with him). He informed the Prophet (peace and blessings be upon him) that he had a slave girl. One day he became angry with her and struck her, and he wanted to free her in place of striking her. The Prophet (peace and blessings be upon him) ordered him to bring her. He brought her, a slave girl. O our brothers, a slave girl. The Prophet (peace and blessings be upon him and his family) said to her: This slave girl is more knowledgeable than those who say that He is in every place, or that He is not in a place. This slave girl said, "In the sky." Did the Prophet (peace and blessings be upon him and his family) rebuke her for saying this, or did he affirm it? He affirmed it and said to him: What is this? What type of evidence is this? Affirmation. So the Sunnah, and praise be to Allah, indicates the exaltation of the Lord (Mighty and Majestic) by speech, and what else? And by action, and what else? And by affirmation. Is there anything beyond these evidences? No.
