Anas bin Malik (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, “Among the inmates of Hell, a person who had led the most luxurious life in this world will be brought up on the Day of Resurrection and dipped in the Fire and will be asked: ‘O son of Adam! Did you ever experience any comfort? Did you happen to get any luxury?’ He will reply: ‘By Allah, no, my Rubb.’ And then one of the people of Jannah who had experienced extreme misery in the life of this world will be dipped in Jannah. Then he will be asked: ‘O son of Adam! Did you ever experience any misery? Did you ever encounter difficulty?’ He will say: “By Allah, no my Rubb, I neither experienced misery nor passed through hardship”.[Muslim].
The Prophet, peace and blessings be upon him, said, “Shall I tell you about the most beloved to me and the closest to my assembly on the Day of Resurrection?” They were silent, so the Prophet repeated himself two or three times. They said, “Yes, O Shall I tell you about the most beloved to me and the closest to my assembly on the Day of Resurrection?” Messenger of Allah.” The Prophet said, “Those with the best character.”Source: Musnad Ahmad
