Al-Hasan said concerning the Ayah,
﴿ إِنَّ عَذَابَهَا كَانَ غَرَامًا ﴾
(𝐕𝐞𝐫𝐢𝐥𝐲, 𝐢𝐭𝐬 𝐭𝐨𝐫𝐦𝐞𝐧𝐭 𝐢𝐬 𝐞𝐯𝐞𝐫 𝐚𝐧 𝐢𝐧𝐬𝐞𝐩𝐚𝐫𝐚𝐛𝐥𝐞, 𝐩𝐞𝐫𝐦𝐚𝐧𝐞𝐧𝐭 𝐩𝐮𝐧𝐢𝐬𝐡𝐦𝐞𝐧𝐭.) Everything that strikes the son of Adam, then disappears, does not constitute an inseparable, permanent punishment. The inseparable, permanent punishment is that which lasts as long as heaven and earth. This was also the view of Sulayman At-Taymi.
﴿ إِنَّهَا سَآءَتۡ مُسۡتَقَرًّ۬ا وَمُقَامً۬ا ﴾
(𝐄𝐯𝐢𝐥 𝐢𝐧𝐝𝐞𝐞𝐝 𝐢𝐭 𝐢𝐬 𝐚𝐬 𝐚𝐧 𝐚𝐛𝐨𝐝𝐞 𝐚𝐧𝐝 𝐚𝐬 𝐚 𝐩𝐥𝐚𝐜𝐞 𝐭𝐨 𝐫𝐞𝐬𝐭 𝐢𝐧.) means, how evil it looks as a place to dwell and how evil it is as a place to rest.
