وقال لهم نبيهم إن آية ملكه أن يأتيكم التابوت فيه سكينة من (2:248) بالانجليزي

(2:248) Their Prophet further informed them, "The sign of his appointment as king from Allah is that during his reign you will get back the Ark, wherein are the means of your peace of mind from your Lord, and which contains the sacred relics of the family of Moses and Aaron, and which is being borne at this time by the angels. *270 Herein is a great Sign for you, if you are true believers."

*270). The Biblical version of this incident is different from the Qur'anic one. The former sheds light, however, on certain details of the incident. It shows that during a military engagement the pagan Philistines had captured the 'Ark of the covenant'. Terrified of the scourge and pestilence which spread wherever they carried the Ark, these pagans placed it on a cart driven by milk cows, and sent it off. (1 Samuel 5-6 - Ed.) Perhaps the Qur'an alludes to this when it mentions angels, since the cart was driverless and it was the angels who kept it in their custody and brought it to the Israelites. The Qur'anic statement, that in the Ark 'lies inward peace for you', can be understood in the light of the Biblical statements that the Israelites regarded the Ark as highly auspicious, and as an emblem of their triumph and victory. When they were deprived of it, they began to feel that they had been deprived of the mercy of God. The return of the Ark, therefore, had a highly salutary effect on them as it strengthened their sagging morale and raised their spirits.
The Qur'anic mention of 'the sacred relics left behind by the house of Aaron' seems to allude to the Tablets of Law bequeathed to Moses on Mount Sinai. The Ark is also said to have contained the original copyof the Torah, which Moses himself had had transcribed and which he had himself handed over to the Levites. The Ark is also supposed to have contained a golden urn holding the manna (Hebrews 9: 2 ff - Ed.), in order that the coming generations might recall God's benevolence to their forefathers during their wandering in the desert. The Ark also probably contained the rod of Moses which was one of the great miracles of God. (Hebrews 9: 5 mentions the rod of Aaron - Ed.)
