SHAFAQNA – The believer must always consider death, hereafter, and the Day of Judgment because these are the preventative elements and the bases of the belief as disbelieving or doubting the hereafter cause mischief as mentioned in Ayahs 1 to 5 of Surah Al-Qiyamah. Imam Jawad (AS) was asked: What is death? Imam (AS) replied: Death is the same as sleep which comes to you every night except the length of the sleep is long and the human being does not wake up from that sleep except on the Day of Judgment . In order to think constantly about death, one must visit the graves of the believers, as Imam Jawad (AS) said: Whoever visits the graves of Muslim brethren and sits next to the grave facing Qiblah and place his hand on the grave and recites Surah Al-Qadr for seven times, will be saved from the great torment .
