إِنَّ هَـٰذَا لَهُوَ حَقُّ ٱلْيَقِينِ
Inna haaza lahuwa haqqul yaqeen
Zaprawdę, to jest prawda całkowitej pewności!
Indeed, this is the truth of certainty.
Ḥaqq al-yaqīn joins truth to certainty, and the tradition has set it beside two related phrases from Surah al-Takathur, ʿilm al-yaqīn and ʿayn al-yaqīn. Read together they have been taught as three degrees: knowing of a fire, seeing the fire, and being burned by it. The surah closes here on the certainty of the event it opened with, after sorting people into three: the foremost, those of the right hand, and the deniers who strayed.
