This excerpt is taken from Sheikh Hafiz Mubashir Hussain Lahori's book Signs of the Day of Judgment in the Light of Authentic Hadiths.
Sign of the Day of Judgment: Heart Attacks will become frequent
وعن أنس بن مالك رضى الله عنه عن النبى صلى الله عليه وسلم قال : إن من أمارات الساعة ..... أن يظهر موت الفجاءة
"It is narrated from Hazrat Anas bin Malik (RA) that the Prophet Muhammad (PBUH) said: Among the signs of the Day of Judgment is that sudden deaths will become frequent."
Reference: Majma' al-Zawa'id (325/7) Sahih al-Jami' (214/5)
Sheikh Albani graded its chain of narration as Hasan (good).
Benefits:
➊ The sudden death of a healthy person without any illness is called death by heart attack.
➋ Frequent deaths due to heart attacks are a sign of the Day of Judgment.
➌ This mentioned sign is at its peak in the present era; every day, without exaggeration, many people are dying due to heart attacks.
➍ It is possible that as the Day of Judgment approaches, the occurrence of this sign will increase.
➎ These couplets are narrated from Imam Bukhari, may Allah have mercy on him:
اغتنم فى الفراغ فضل ركوع / فعسى أن يكون موتك بغتة
Consider your free time precious and perform some Ruku (bowing in prayer); your sudden death is near.
كم صحيح رأيت من غير سقم / ذهبت نفسه الصحيحة فلتة
You see many healthy people whose healthy lives suddenly end.
Hafiz Ibn Hajar, may Allah have mercy on him, states: It is a strange coincidence that Imam Bukhari, may Allah have mercy on him, also died in a similar sudden manner.
