وَمَا أَصَابَكُم مِّن مُّصِيبَةٍ فَبِمَا كَسَبَتْ أَيْدِيكُمْ وَيَعْفُو عَن كَثِيرٍ
Whatever affliction that may visit you is because of what your hands have earned, and He excuses many [an offense of yours].
Agha Ali Puya Commentary
Commentary on Quran 42:30
[Pooya/Ali Commentary 42:30] Refer to the commentary of Nisa: 79. Evil is not normal. The nature of Allah's creation is orderly, harmonious and normal. When twisted and corrupted, it becomes evil. The hardships the righteous suffer in the cause of Allah is a trial to distinguish them from ordinary people .
Ali Muhammad Fazil Chinoy Commentary
Commentary on Quran 42:30-43
Under subject to trial (1) to pray, (2) to participate in crusade or (3) follow a Divine Light, a faithful may succeed or fail. In case of success, his faith is confirmed, and in case of failure, punishment is inevitable, as per the decree of crime in the world or Eternity or at both places. Mental misgivings unless brought out in action are solved by oral penance, and false claims of hypocrites shall take them to the lowest grade of hell – vide Couplet 33 above. Couplet 41 is a Divine sanction to the 12th Divine Light to avenge, on Resurrection (1) Bani Umayyah, (2) falsifiers of Divine Commands, and (3) their enemies, and Couplets thereafter portray their behaviour, on seeing Divine Light, Ali, the Her, on resurrection.
