According to search-discovered classical Islamic scholarship, the concept of Al-Istirakh (الاصطراخ), or 'fervent cries', refers to the intense, desperate shrieks for help from the inhabitants of Hellfire, as vividly described in Quran 35:37. Al-Tabari's linguistic analysis of the verb 'yastarikhoona' highlights its meaning as not just a cry of pain, but a loud plea for rescue. This is not a plea for mercy, but an impossible request for a second chance to return to the world. Ibn Kathir explains in his tafsir that this cry is a manifestation of their ultimate and eternal regret, which comes only after the reality of their punishment, described in the preceding verse (35:36), has become absolute. The divine response to their cry confirms the finality of their state, as they had already received ample opportunity and warnings during their lives. Thus, the synthesis of these verses establishes Al-Istirakh as a powerful eschatological concept representing the final, unanswered despair of those who rejected faith.
