سورة التوبة

Ali ibn Ibrahim (may Allah have mercy on him): This verse was also revealed concerning Jadd ibn Qays, at the time when he said to his people: "Do not go out to battle in the heat."

Imam Ali (peace be upon him): Farqad al-Bajali said: I heard Ali (peace be upon him) saying: "O people of Kufa! I am amazed at you and at the people of Sham! For their commander disobeys Allah and yet they obey him, while your commander obeys Allah and you disobey him (the commander). If I tell you to march toward the enemy during the heat of hot days, you say: 'These days are very hot.' And whenever I order you to go toward them (the enemies) in winter, you say: 'The cold prevents us!' Do you suppose that your enemy does not feel the heat as you feel it!? Rather, you resemble a people to whom the Messenger of Allah (peace be upon him and his family) said: 'March forth in the way of Allah [for jihad].' Their elders said: 'Do not march forth in the heat.' So Allah said to His Prophet (peace be upon him and his family): قُلْ نارُ جَهَنَّمَ أَشَدُّ حَرًّا لَوْ کانُوا یَفْقَهُونَ [Say: The fire of hell is much severer in heat. Would that they understood]."
