عَنْ عُبَادَةَ بْنِ الصَّامِتِ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ حَرَّمَ الله عَلَيْهِ النَّار»
Translation

Jabir reported that God's messenger said, “Two things have results." On being asked by a man what these two things were, he replied, “He who dies a polytheist will enter hell, and he who dies worshipping God alone will enter paradise." Muslim transmitted it.
