The Ruling on Raising the Hands During the Friday sermon Supplication
Question :
What is the ruling on raising the hands during the supplication of the Friday sermon, I used to do this but then somebody told me that it was forbidden after the prayer, however, he did not give me any proof.
Answer:
It is not legislated for one to raise their hands during the A Friday sermon; the Prophet's Companions, may Allah be pleased with them, objected to Bishr bin Mirwaan when he did so. This is legislated for only two occasions: the prayer for rain and the prayer for halting the rain. The proof of this the Hadith in which Anas narrated that a man entered the Masjid while the Prophet was delivering a sermon. The man said, "The wealth (crops) is destroyed." The Prophet raised his hands and supplicated. Anas mentioned that the same man came the following Friday and said, "O Messenger of Allah, the wealth )crops) is drowned." Again, the Prophet ﷺ raised his hands and said:
"O Allah! Around us, not upon us."
This Hadith was recorded by Muslim in the Book of the Prayer for Rain.
Therefore, the Khatib (one delivering the sermon) only raises his hands on these two occasions, and the people only raise their hands when the Khatib does so because the Companions raised their hands with the Prophet (on both occasions).
