If you say: Why did he return and connect with the letter 'fa' his saying, 'Do they feel secure from the plan of Allah?' I say: It is a repetition of his saying, 'Do the people of the towns feel secure?' And the plan of Allah is a metaphor for taking the servant from where he does not perceive. And for his being led into temptation. Therefore, it is upon the wise person to be in fear of the plan of Allah, like a warrior who fears from his enemy the ambush, the night attack, and the treachery. And from Al-Rabi' ibn Khuthaym, that his daughter said to him: Why do I see people sleeping and I do not see you sleeping? He said: O my daughter, indeed your father fears the night attack, referring to His saying, 'So that Our punishment comes upon them by night.'
