Some believe that the word /awwalin/ ' old' , in this verse, refers to the generations of Noah, 'Ad and Thamud; and the word /akharin/ following' refers to the generations after them; such as those of Lot and Pharaoh. But taking note of the term /nutbi'uhum/ ...shall we make follow (generations) follow them , which is in the future tense and/alamnuhlik/ Did We not destroy...
, which is in past tense it, then, becomes clear that 'Old' refers to all the old generations who were destroyed by Allah's Will , and ' following ' refers to the sinners of the Prophet's (p.b.u.h.) time or those who will come into being after that and will commit sins and corruptions. And, so, the warning: Ah woe, that Day, to the Rejecters of Truth. The words 'That Day', here, means the Hereafter, when they will have their main punishment and retribution.
The repetition of the verse is for emphasis, though they may have a chastisement even in this world. Then, it attracts their attention to the period of gestation which shows them the power and the authority of the Creator and also the abundance of His blessings to Man. Consequently, they understand His force, in regard to the Resurrection, and, they, themselves, owe Allah for His numerous blessings and respect Him. Did We not create you from a base fluid?
The which We placed in a safe abode, firmly fixed) . A place where all the conditions for life, growth and protection of the foetus exists. It is so amazing and interesting that it causes everyone to wonder. For a period (of gestation) determined? A period of time that no one knows, but Allah During this period many changes occur and every day the foetus enters a new phase in its development in that abode.
For We determine; and We are the best to determine, (and then Resurrection is easy for Us to portend) . This is the same reason for which the Qur'an has emphatically used in proving the possibility of the Resurrection. For example, in the beginning verses of Sura Hajj No.22, Mankind's attention is attracted to the process of their own physical growth; from lifeless matter to seed, fertilized ovum, foetus, child, youth, aged and death!
How can they doubt that the author of all these wonderful stages in their lives, in this world, each of which is as important as the Resurrection, can also give them another kind of life after the end of this probationary life? How different is dust from sperm! Ah woe, that Day, to the Rejecters of Truth.
