SurahAn-NāsMeccanSeeking refuge from the whispering of Iblīs and his allies

Key Fiqh IssueWaswās (whispering/obsessive doubt) and the legal maxim: certainty is not removed by doubtCore legal maximOne of the five great Islamic legal maxims governs all doubt-in-worship questions

School ComparisonAll four schools: al-yaqīn lā yazūlu bi-l-shakk (certainty is not removed by doubt) is the governing principle; waswās does not break wuḍūʾ unless certain; waswās does not break fasting; prayer counts as complete unless certain of errorUnanimous maxim applicationThe most protective stance against Iblīs's tool of obsessive doubt

Uṣūl PrincipleAl-yaqīn lā yazūlu bi-l-shakk certainty is not removed by doubtOne of the five great maximsThe juristic antidote to waswās preserves worship validity against Iblīs's obsessive whispering

Al-Qurṭubī completes his al-Jāmiʿ li-Aḥkām al-Qurʾān with this surah, which he identifies as the most practically significant Qurʾānic text for combating obsessive religious doubt. The waswās (whispering) of Iblīs and his allies who "whispers in the breasts of people" is identified by al-Qurṭubī as the primary mechanism behind obsessive-doubt afflictions (waswās al-qahrī) that plague worshippers with endless concerns about the validity of their wuḍūʾ, prayer, and other acts.

Al-Qurṭubī derives the legal antidote from the great maxim al-yaqīn lā yazūlu bi-l-shakk (certainty is not removed by doubt) one of the five great Islamic legal maxims that governs all doubt-in-worship scenarios. Practical applications: if a person performed wuḍūʾ and then doubts whether they broke it, the wuḍūʾ remains valid (the certainty of wuḍūʾ is not removed by the doubt). If a person is fasting and doubts whether they ate, the fast continues. If a person praying doubts whether they prayed three or four rakaʿāt, they count the lesser (more certain) number and complete the prayer. The Qurʾānic refuge (Al-Falaq + An-Nās together) is itself the prescribed spiritual remedy for waswās.

مِن شَرِّ الْوَسْوَاسِ الْخَنَّاسِ الَّذِي يُوَسْوِسُ فِي صُدُورِ النَّاسِ Min sharri l-waswāsi l-khannāsi lladhī yuwaswisu fī ṣudūri l-nās Meaning: "From the evil of the retreating whisperer who whispers in the breasts of people" Al-Qurṭubī: "al-khannās" (the retreater retreats when Allah is remembered) the prescribed remedy is dhikr (remembrance of Allah); when waswās attacks during worship, increasing the remembrance of Allah drives away the whisperer; the legal maxim (certainty over doubt) is the legal antidote, and dhikr is the spiritual antidote.

مِنَ الْجِنَّةِ وَالنَّاسِ Mina l-jinnati wa-l-nās Meaning: "From among the jinn and mankind" Al-Qurṭubī: waswās comes from two sources Iblīs and jinn, and human companions who encourage doubt and sin; al-Qurṭubī derives that obsessive doubt can be reinforced by human companions as much as by Iblīs; choosing righteous companions is therefore also a protection against waswās.

Al-yaqīn lā yazūlu bi-l-shakk (certainty is not removed by doubt) is one of the five great Islamic legal maxims unanimous across all four schools and the primary juristic tool against obsessive worship-doubt.
Wuḍūʾ doubt: if a person performed wuḍūʾ and doubts whether they broke it, the wuḍūʾ remains valid the certainty of wuḍūʾ is not displaced by the doubt.
Fasting doubt: if a person doubts whether they ate while fasting, the fast continues the certainty of the fast-state is not displaced by doubt.
Prayer rakaʿāt doubt: count the lesser (more certain) number and complete all schools apply this consistently.
Al-Qurṭubī concludes his 20-volume tafsīr with this surah's maxim an appropriate ending: the entire fiqh edifice built through 114 surahs rests on the certainty of divine truth (yaqīn) and cannot be dismantled by the doubt that Iblīs whispers against it.
