* تفسير Tafsir al-Jalalayn مصنف و لم يتم تدقيقه بعد
{ وَقَالَ ٱلَّذِينَ كَفَرُواْ لَوْلاَ نُزِّلَ عَلَيْهِ ٱلْقُرْآنُ جُمْلَةً وَاحِدَةً كَذَلِكَ لِنُثَبِّتَ بِهِ فُؤَادَكَ وَرَتَّلْنَاهُ تَرْتِيلاً }And those who disbelieve say, ‘Why has the Qur’ān not been revealed to him all at once?’, as the Torah, the Gospel and the Book of Psalms [were]. God, exalted be He, says: We have revealed it, thus, in parts, [it is], that We may strengthen your inner-heart with it, and We have arranged it in a specific order, that is to say, We produce it in stages one part after another, gradually and deliberately, in order to facilitate its comprehension and its memorisation.
