Self-discipline and character
"He has succeeded who purifies it, And he has failed who instills it [with corruption]" (91:9–10). Character is trained little by little: "the most beloved deed to Allah is the most regular and constant even if it were little" (Bukhārī 6464 Ṣaḥīḥ (sound)).
وَنَفْسٍ وَمَا سَوَّىٰهَا٧ فَأَلْهَمَهَا فُجُورَهَا وَتَقْوَىٰهَا٨ قَدْ أَفْلَحَ مَن زَكَّىٰهَا٩ وَقَدْ خَابَ مَن دَسَّىٰهَا١٠
Transliteration: wanafsin wamā sawwāhā · fa-alhamahā fujūrahā wataqwāhā · qad aflaḥa man zakkāhā · waqad khāba man dassāhā
And [by] the soul and He who proportioned it And inspired it [with discernment of] its wickedness and its righteousness, He has succeeded who purifies it, And he has failed who instills it [with corruption].

For each one are successive [angels] before and behind him who protect him by the decree of Allah. Indeed, Allah will not change the condition of a people until they change what is in themselves. And when Allah intends for a people ill, there is no repelling it. And there is not for them besides Him any patron. 13:11

What it means
Nafs, tazkiya, mujāhada. Nafs is the self or soul, including its desires. Tazkiya is purification — the same root as zakāh — meaning both cleansing and growth. Mujāhada is striving against the self. Khuluq is character.
What the Quran says
The soul and its purification (91:7–10). "And [by] the soul and He who proportioned it And inspired it [with discernment of] its wickedness and its righteousness, He has succeeded who purifies it, And he has failed who instills it [with corruption]" (91:7–10), Meccan. The verse says humans are given the knowledge of both, and their success depends on what they do with it.
Holding the self back (79:40–41). "But as for he who feared the position of his Lord and prevented the soul from [unlawful] inclination, Then indeed, Paradise will be [his] refuge" (79:40–41), Meccan.
Striving and guidance (29:69). "And those who strive for Us — We will surely guide them to Our ways. And indeed, Allah is with the doers of good" (29:69). The effort comes first, and guidance follows.
The self that urges evil (12:53). "And I do not acquit myself. Indeed, the soul is a persistent enjoiner of evil, except those upon which my Lord has mercy" (12:53). In Sura Yusuf, this is spoken at the end of the story of the minister's wife (Ibn Kathir and others differ on whether the speaker is Joseph or the woman; that discussion has not yet been consulted).
Change begins inside (13:11). "Indeed, Allah will not change the condition of a people until they change what is in themselves" (13:11). The verse is about a people; applying it to an individual's habits is a common extension.
What the Prophet (pbuh) taught
Small and steady. ʿAʾisha (ra) reports the Prophet (pbuh) as saying: "Do good deeds properly, sincerely and moderately and know that your deeds will not make you enter Paradise, the most beloved deed to Allah is the most regular and constant even if it were little" (Bukhārī 6464 Ṣaḥīḥ (sound)). Moderation and constancy, not bursts of effort, and no pride in one's deeds.
Good character weighs most. "There is nothing heavier than good character put in the scale of a believer on the Day of Resurrection" (Abū Dāwūd 4799 Ṣaḥīḥ (sound) — al-Albānī, narrated by Abu al-Dardaʾ; al-Albani: ṣaḥīḥ).
How scholars have understood it
Training the soul. J. Winter) — comparing training the soul to training an animal, by gradual habit — and Miskawayh's Tahdhīb al-Akhlāq and Naṣīr al-Dīn al-Ṭūsī's Akhlāq-i Nāṣirī, which follow Aristotle in treating virtue as a balanced mean formed by repetition. None of these texts was read; the Bukhari hadith above states the same principle of steady practice.
What research shows
Childhood self-control predicts adult life. Established (correlational.) The Dunedin study "followed 1,037 children from birth to age 32". Children with lower self-control, as rated by teachers, parents and themselves, were more likely as adults to have worse physical health, substance dependence, money and credit problems, and criminal convictions — "after controlling for social class and IQ score" (Moffitt et al., 2011, as reported).
Habits take time. [Moderate; small study.] In Lally and colleagues (2010), 96 people chose a new daily habit (82 completed). The "average time to reach maximum automaticity was 66 days", ranging from 18 days to a predicted 254. Missing one day made little difference; many missed days lowered the habit's strength (BPS summary). This fits the hadith: little and regular.
"Willpower runs out" did not replicate. Established (for the replication.) The "ego depletion" idea — that self-control is a fuel that runs down — was tested in 23 laboratories with 2,141 participants. The effect was d = 0.04 (95% CI −0.07 to 0.15), not reliably different from zero (Hagger et al., 2016).
In daily life
Start small and keep it up: two minutes of Quran, two units of extra prayer, one act of kindness — every day (Bukhārī 6464 Ṣaḥīḥ (sound)).
Expect about two months before a new habit feels natural (Lally et al.), and don't give up after a missed day.
Change the setting, not only the will: remove temptations, set reminders, choose good company.
Work on character, not only rituals: patience, honesty, gentleness weigh most (Abū Dāwūd 4799 Ṣaḥīḥ (sound) — al-Albānī).
For the heart and mind
If you keep failing, the Quran expects struggle: "the soul is a persistent enjoiner of evil, except those upon which my Lord has mercy" (12:53). Falling and getting up again is the path, not a sign that you are not on it.
If you are trying to stop an addiction, willpower alone is rarely enough; ask for help — a doctor, a counsellor, a support group. Seeking help is part of striving (29:69).
Questions readers ask next
Can character really change?
The Quran's call to purify the soul (91:9) assumes it can; the research on habits shows it takes time and repetition.
Why "little but constant"?
Because steady habits last; bursts of effort fade (Bukhārī 6464 Ṣaḥīḥ (sound); Lally et al.).
Is willpower a limited resource?
The large replication found no reliable "ego depletion" effect (Hagger et al., 2016).
Who is speaking in 12:53?
Commentators differ (Joseph or the minister's wife); not checked here.
Does 13:11 apply to individuals?
It speaks of "a people"; using it for personal change is a common extension.
