Surah 14. Ibrahim
Ayah 5
٥. وَلَقَدْ أَرْسَلْنَا مُوسَىٰ بِـَٔايَـٰتِنَآ أَنْ أَخْرِجْ قَوْمَكَ مِنَ ٱلظُّلُمَـٰتِ إِلَى ٱلنُّورِ وَذَكِّرْهُم بِأَيَّىٰمِ ٱللَّهِ ۚ إِنَّ فِى ذَٰلِكَ لَـَٔايَـٰتٍ لِّكُلِّ صَبَّارٍ شَكُورٍ
[5] We sent Moses also before this with Our Signs: and We commanded him, "Bring your people out of all kinds of darkness into Light and admonish, them to learn lessons from the Divine History."8 There are great Signs9 in this for every steadfast and grateful person.10
8The Arabic word (ayyam) technically means memorable historical events. Therefore (Ayyam-u-Allah) (Divine History) implies all those eventful chapters of human history which mention the rewards and punishments that were meted out to the great personalities and nations according to their deeds in the past ages.
9Those historical events are Signs in this sense that their proper and intelligent study provides proofs of the fact that there is only one God: and that the Law of Retribution is universal and is based absolutely on the differentiation between the knowledge and moral practice of the Truth and falsehood: that this Law also requires another world (the Hereafter) for its due fulfillment. Moreover, these events contain Signs that serve as warnings against the evil consequences of building up systems of life on false creeds and theories, and help one to learn lessons from them.
10Though these Signs are always there, only those persons learn lessons from them who remain steadfast in trials and appreciate the blessings of Allah rightly and are grateful to Him. Obviously, frivolous and ungrateful persons cannot learn any lesson from these Signs, even though they might grasp their significance.
