Preparing for DeathAs A Muslim, you should be prepared for death at all times whether it is day or night, whether you are sleeping or awake. You can practically prepare for it with the following:-
1. Faith in the phrase of Tawhid and applying it.
2. You must be steadfast in performing our five compulsory daily prayers in congregation (men). Regarding the prayer, you should also pray those prayers that are highly recommended that are voluntary in nature, that are performed in the night and that includes both the Witr prayer and the Sunnah prayers in general.
3.You must recite the Qur’an, contemplate its meanings and apply its commands and laws. You should recite it late at night and at the beginning and the end of the day. It is also recommended for you to recite it before the compulsory prayers. Finally, you should finish reading the Qur’an in its entirety at least once or twice a month.
4.Study the Sunnah of the Prophet (Sallallahu Alayhi wa Sallam), follow what he orders and abstain from what he forbids.
