Abdullah Ali's faithful transaltion of a section concerning the meditation of death from Ibn Rajab's famous work on yearly devotions is much needed in our culture of forgetfulness.
He has chosen a work of immense value to introduce speakers of English. The Prophet (ﷺ) said, 'Make much mention of the Destroyer of Delights' - meaning death. This is not morbid reflection but rather one that reminds us that the gift of life is fragile and fleeting, and its foremost purpose is as a preparation for the Hereafter.
All things end including this world, but what is coming never ends. In remembering death as a daily practice, one is reminded to use each and every day successfully as a preparation for eterneity. This wonderful work is an excellent place to start.
