What is the definitive ruling on raising the hands during supplication and during qunut?

The questioner : May Allah reward you, O honorable Shaykh. We want the definitive ruling on raising the hands during supplication and during qunut.

The Shaykh : The definitive ruling in this matter is that the original practice in supplication is to raise the hands. That is, the original etiquette of supplication is for a person to extend his hands to his Lord, like a poor beggar. This is indicated by the saying of the Prophet (peace and blessings be upon him): and the saying of the Prophet (peace and blessings be upon him) regarding the man: except where the Sunnah indicates not raising them.
This issue has conditions, or rather categories. The first category is where the Sunnah has come with leaving it, such as raising the hands in supplication during the Friday sermon. The Companions (may Allah be pleased with them) criticized Bashir ibn Marwan for raising his hands in the Friday sermon during supplication, except in one case: supplication for rain or for the cessation of rain. It is established from the Prophet (peace and blessings be upon him) that he raised his hands in the Friday sermon. A man entered on a Friday while the Prophet (peace and blessings be upon him) was delivering the sermon to the people and said: “O Messenger of Allah! The wealth has been destroyed and the roads have been cut off, so call upon Allah to relieve us.” The Prophet (peace and blessings be upon him) raised his hands and said: The people raised their hands with him. Then Allah sent down a cloud like a shield. When it reached the middle of the sky, it spread out, thundered, and flashed, and rain fell before the Prophet (peace and blessings be upon him) descended from the pulpit. He did not descend until the rain was pouring from his beard. The rain continued for a full week. In the second Friday, a man, or the first man, entered and said: “O Messenger of Allah! The wealth has been drowned and the buildings have collapsed, so call upon Allah to hold it back from us.” The Prophet (peace and blessings be upon him) raised his hands and said: He pointed to the sides, and wherever he pointed, the clouds parted. The people went out walking in the sun. So in the case of supplication for rain, a person raises his hands to his Lord (Mighty and Majestic), even in the Friday sermon.
The second condition is where the apparent Sunnah indicates not raising the hands, and that is in supplication during the prayer. It appears that the Messenger (peace and blessings be upon him) did not raise his hands. He would sit between the two prostrations and say: It is not narrated from him that he raised his hands, despite the Companions’ eagerness to follow his words and actions in his prayer and transmit them.
The third condition is where the Sunnah has come with raising the hands, as is established in the supplication on al-Safa and al-Marwah, and in the supplication at 'Arafah, and others. Some scholars have counted more than thirty places where the Sunnah explicitly mentions raising the hands. The matter in this is clear: a person raises his hands.
The fourth is where the Sunnah has not come with either this or that. The original practice is to raise the hands, and if one does not raise them, there is no harm. There is no doubt that raising the hands in this case is an increase in supplication to Allah (Mighty and Majestic) and hope in His mercy. For this reason, it is among the etiquettes of supplication, except where the Sunnah has come with the contrary. The issue does not lack the four categories I mentioned, meaning that raising the hands falls into four categories: where the Sunnah has come with raising them, where it has come explicitly with not raising them, where the apparent indication is not raising them, and what is devoid of these three categories.
