The Prophet* said: ‘Righteousness (birr)7 is what causes an expansion within your breast, and iniquity (ithm) is what sows intrigue (ḥāka) in your breast, even if those who are authorised to give out legal rulings provide you with [legal] fatwā upon fatwā [to the contrary]. Ibn Ḥanbal, al-Musnad, vol. 4, p. 194; Tirmidhī, Nawādir al-uṣūl, vol. 1, p. 239.
