(Al-A’Alaa) 87 : 17
وَالْآخِرَةُ خَيْرٌ وَأَبْقَىٰ
While the Hereafter it is the best and eternal.
The believer who understood the aim of life from Adhikr utilizes this temporary worldly life as cultivation land for the eternal Hereafter, and will propagate Adhikr to the entire mankind irrespective of caste, religion, sex, color, nation, etc., for encouraging them to do so. See explanation 18:46; 42:20 and 64:15-16.
