Thabit Ibn Qays[RA], a people of paradise
Al-Bukhari recorded that Anas bin Malik said, “The Prophet missed Thabit bin Qays and a man said, `O Allah’s Messenger! I will find out about his news.’ That man went to Thabit and found him sitting at home with his head lowered and asked him, `What is the matter’ Thabit said, `An evil matter!’ And he said that he used to raise his voice above the voice of the Prophet . He feared that his good deeds would be useless and he would be among the people of the Fire. The man went back to the Prophet and conveyed Thabit’s statement and returned to Thabit with a wonderfully good news. The Prophet said,
«اذْهَبْ إِلَيْهِ فَقُلْ لَهُ: إِنَّكَ لَسْتَ مِنْ أَهْلِ النَّارِ، وَلَكِنَّكَ مِنْ أَهْلِ الْجَنَّة»
(Go back to him and tell him this news; you are not among the people of the Fire. Rather, you are among the dwellers of Paradise.)” Al-Bukhari collected this Hadith with this wording.
Anas commented, “We used to see Thabit walk among us knowing that he was (to be) among the dwellers of Paradise. During the battle of Yamamah, our forces suffered retreat. Suddenly, Thabit bin Qays bin Shammas came, having put on his Hanut and shrouds, and said, `The worst habit is the one you acquire from your enemy and do not set a bad example for your companions.’ And he went on fighting until he was martyred, may Allah be pleased with him.”
