Abu Sa’id al-Khudri reported: The Messenger of Allah (ﷺ), said, “Beware of the intuition of the believer. Verily, he sees with the light of Allah.” Then, the Prophet recited the verse, “Verily, in that are signs for those of discernment.” (15:75)
[Sunan al-Tirmidhi 3127]
عن أبي سعيد الخدري قال قال رسول الله صلى الله عليه وسلم اتقوا فراسة المؤمن فإنه ينظر بنور الله ثم قرأ إِنَّ فِي ذَٰلِكَ لَآيَاتٍ للْمُتَوَسِّمِين
Ibn al-Qayyim said, “It is a light that Allah bestows in the heart of his servant, by which he distinguishes between truth and falsehood, advantage and disadvantage, the honest and the liar.”
