According to search-discovered classical Islamic scholarship, the principle of not sending divine signs to satisfy whims is a cornerstone of Quranic theology, articulated in Surah Al-Hijr, verses 7-8. This concept addresses the demand of disbelievers to see angels as proof of prophethood. The definitive Islamic understanding, as explained by authorities like Ibn Kathir and Al-Qurtubi, is that Allah's actions are governed by divine wisdom and truth (al-Haqq), not frivolous human challenges. The thematic synthesis of these verses reveals that angels are not sent as a spectacle; their descent is a matter of utmost gravity, occurring only for a decisive purpose: either to deliver revelation or to enact an irreversible judgment. Al-Tabari confirms the historical context of the Quraysh's mockery, while Al-Qurtubi clarifies that the 'truth' they bring is the final verdict. Therefore, if Allah were to grant their request, it would not be a means of guidance but a signal for their immediate punishment, leaving no room for respite or repentance. This principle underscores that the demand for such a sign is, in essence, a request for one's own destruction, and Allah's refusal is a form of hidden mercy, keeping the door of tawbah (repentance) open.
