Messenger of Allah ﷺ once stood up delivering a sermon and mentioned the trial which people will face in the grave. When he mentioned that, the Muslims started shouting loudly.
أَنَّهُ سَمِعَ أَسْمَاءَ بِنْتَ أَبِي بَكْرٍ ؓ تَقُولُ قَامَ رَسُولُ اللَّهِ ﷺ خَطِيبًا فَذَكَرَ فِتْنَةَ الْقَبْرِ الَّتِي يَفْتَتِنُ فِيهَا الْمَرْءُ فَلَمَّا ذَكَرَ ذَلِكَ ضَجَّ الْمُسْلِمُونَ ضَجَّةً
