عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ: سَأَلْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ عَنْ مَوْتِ الْفَجْأَةِ، فَقَالَ: ((رَاحَةٌ لِلْمُؤْمِنِينَ، وَأَخْذَةُ أَسَفٍ لِلْفَاجِرِ))
It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: I asked the Messenger of Allah (peace and blessings be upon him and his family) about sudden death. He (peace and blessings be upon him and his family) said: For the believer, it is a relief, but for the sinner, it is a seizure of wrath.
