Qaf 50:11
The three-verse passage 50:9–11 turns around a single image: rain (māʾ mubārak) → gardens → ḥabb al-ḥaṣīd (the harvested grain) → nakhl bāsiqāt (lofty palms) → ṭalʿ naḍīd (closely-tiered blossoms) → "kadhālika al-khurūj" (so will be the coming-forth from the graves).
رِّزْقًا لِّلْعِبَادِ ۖ وَأَحْيَيْنَا بِهِۦ بَلْدَةً مَّيْتًا ۚ كَذَٰلِكَ ٱلْخُرُوجُ
As sustenance for the servants. And We revive thereby a dead town. Likewise is the resurrection
Qaf 50:11 · Translation: talal-itani
Image
Verse 11 is the resurrection-clasp of the passage: the scene of agricultural bounty is bound in a single line to the emergence in the hereafter.
Observation
The date palm (Phoenix dactylifera) is a tropical/sub-tropical arid-climate plant; it tolerates long drought, and once water arrives its life cycle restarts and its blossoms (ṭalʿ) array in tight order. "Bāsiqāt" — tall-growing; the palm rises vertically up to thirty metres. The passage's botanical observation rests on the daily knowledge of an agrarian society; modern agronomy does not reformulate it, only confirms the soundness of the observation.
Exegesis
Al-Rāzī (Mafātīḥ al-Ghayb) holds that this passage carries a deliberate parallel between "rizq" and "resurrection" — the soil's nourishing of the human (bread, fruit) and the soil's bringing-forth of human beings (rising from the graves) are two faces of one image. The word "iḥyāʾ" (giving life) is the same in both scenes.
