Is the following Hadith authentic: "And after the people of Hellfire have entered Hellfire, and the people of Paradise have entered Paradise, a caller will proclaim, 'Are you pleased, O Muhammad?' He will say, 'By Allah, my Lord, I am not pleased while even one of my Ummah is in the Fire...'" to the end of the Hadith?

This lengthy context is not found in the Sunnah collections but has spread through social media. However, the principle of monotheists being taken out of Hellfire is as firmly established as the sun in authentic hadiths. Among these is what Al-Bukhari and Muslim narrated in their Sahih collections from Anas ibn Malik, may Allah be pleased with him, concerning the Prophet's greatest intercession, peace and blessings be upon him. In it, he will intercede for the believers three times to bring out whoever has in his heart the weight of a barley-grain, or an atom, or the lowest, lowest, lowest weight of a mustard seed of faith. In another, fourth narration by Al-Hasan Al-Basri from Anas, he intercedes for whoever said, "Lā ilāha illallāh" (There is no god but Allah), whereupon Allah Almighty says: "By My Glory, My Majesty, My Grandeur, and My Magnificence, I shall certainly take out of it whoever said 'Lā ilāha illallāh'."
