from Ubadah bin As-Samit, he said: "I entered upon him while he was dying, so I cried, and he said: "There now, why are you crying? For by Allah, if I am a martyr , then I will intercede for you, and if I can I will benefit you,' then he said: 'By Allah! There is no Hadith which I heard from the Messenger of Allah ﷺ which is good for you but I narrate it to you today, while I am near death. I heard the Messenger of Allah ﷺ say: "Whoever testifies to La Ilaha Illallah and that Muhammad is the Messenger of Allah, then Allah has forbidden the fire for him." (Using translation from Tirmidhī 2638)
مَهْلًا لِمَ تَبْكِي؟ فَوَاللهِ لَئِنْ اسْتُشْهِدْتُ لَأَشْهَدَنَّ لَكَ وَلَئِنْ شُفِّعْتُ لَأَشْفَعَنَّ لَكَ وَلَئِنْ اسْتَطَعْتُ لَأَنْفَعَنَّكَ ثُمَّ قَالَ وَاللهِ مَا حَدِيثٌ سَمِعْتُهُ مِنْ رَسُولِ اللهِ ﷺ لَكُمْ فِيهِ خَيْرٌ إِلَّا حَدَّثْتُكُمُوهُ إِلَّا حَدِيثًا وَاحِدًا سَوْفَ أُحَدِّثُكُمُوهُالْيَوْمَ وَقَدْ أُحِيطَ بِنَفْسِي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللهِ حُرِّمَ عَلَى النَّارِ
