If one says: "By Allah! I will not speak today"
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا عَبْدُ الْوَاحِدِ، حَدَّثَنَا الأَعْمَشُ، عَنْ شَقِيقٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم كَلِمَةً وَقُلْتُ أُخْرَى " مَنْ مَاتَ يَجْعَلُ لِلَّهِ نِدًّا أُدْخِلَ النَّارَ ". وَقُلْتُ أُخْرَى مَنْ مَاتَ لاَ يَجْعَلُ لِلَّهِ نِدًّا أُدْخِلَ الْجَنَّةَ.
Narrated `Abdullah: Allah's Messenger (ﷺ) said a sentence and I said another. He said, "Whoever dies while he is setting up rivals along with Allah (i.e. worshipping others along with Allah) shall be admitted into the (Hell) Fire." And I said the other: "Whoever dies while he is not setting up rivals along with Allah (i.e. worshipping none except Allah) shall be admitted into Paradise."
