A seed yielding a fixed 700-fold return per growth cycle, without specifying the seed or its cycle length. This omission is modelled as a free parameter T in a compound-growth function N(t) = N0 700^t/T, with representative cycle lengths anchored to reported growth cycles of real seed-bearing species and the model’s instantaneous rate of growth derived in closed form. The model is then extended to the verses that condition the multiplier itself on how the giving is done: a collapse to zero for insincere giving, a bounded range for sincere giving, and a late-life recurrence of that same collapse tied to a giver’s remaining time and dependents. A structurally different promise in Surah al-Qadr – that a single night can be worth more than a thousand months – is examined separately and modelled as an open-ended floor on the starting value of a deed rather than an extension of the seed model’s own rate.
