مَتَٰعٌ قَلِيلٌ وَلَهُمْ عَذَابٌ أَلِيمٌ
3:198; 4:78.
Commentary:
False claimants to Divine revelation may enjoy a limited respite but their life is sure to be cut short and before they have made any headway, they die an ignominious death. According to the Quran a person who falsely claims to have received Divine revelation and to have been entrusted with a Divine mission cannot enjoy a long respite—much less the period which the Holy Prophet lived after he laid claim to prophethood.
