The three questions that will be asked in the grave.

قال صلى الله عليه و آله و صحبه و سلم

.و الذي نَفْسُ مُحَمَّدٍ بِيَدِهِ إِنَّ مَثَلَ المؤمِنِ كَمَثَلِ النَّحْلَة : أَكَلَتْ طَيِّبَاً و وَضَعَتْ طَيِّبَاً و وَقَعَتْ فَلَمْ تَكْسِرْ و لَمْ تُفْسِدْ

The Prophet said:

"By the One in whose hand is the soul of Muḥammad, the believer is like a bee which eats what is tayyib and lays what is tayyib. When it lands on something it does not break or ruin it." (narrated by Al Imam Aḥmad on the authority of Abdullah bin Amr)
