Surat An-Nahl (69-70)

{ثُمَّ كُلِي مِن كُلِّ الثَّمَرَاتِ فَاسْلُكِي سُبُلَ رَبِّكِ ذُلُلاً يَخْرُجُ مِن بُطُونِهَا شَرَابٌ مُّخْتَلِفٌ أَلْوَانُهُ فِيهِ شِفَاء لِلنَّاسِ إِنَّ فِي ذَلِكَ لآيَةً لِّقَوْمٍ يَتَفَكَّرُونَ} (النحل : 69 )

69- Then, eat from all fruits and suck the nectar of flowers and go in the ways which Allah made easy for you such as wilderness and forests then go back to your homes by a natural disposition Allah instilled in them to know what they should eat, how to go back, and how to build their beautiful similar cells. Honey comes out of their bellies with different colors: White, red, yellow, and black in which there is cure for people from different diseases as was proved by modern medical experiments.

All these are great sings to the power and good creation of Allah, and it is not created out of coincidence or nature for people who reflect, consider, and understand to take lessons and to believe in Allah.

{وَاللّهُ خَلَقَكُمْ ثُمَّ يَتَوَفَّاكُمْ وَمِنكُم مَّن يُرَدُّ إِلَى أَرْذَلِ الْعُمُرِ لِكَيْ لاَ يَعْلَمَ بَعْدَ عِلْمٍ شَيْئاً إِنَّ اللّهَ عَلِيمٌ قَدِيرٌ} (النحل : 70 )

70- O people, Allah created you after you had been nothing, and it is He who causes you to die as children, young, or grown up. Some of you live long until their minds and power become weak and inflicted by disability and feeble-mindedness, so they lose all senses after they had been sound and healthy. Indeed, Allah knows your conditions and ages, and is able over everything such as increasing or decreasing ages.

The Messenger of Allah (peace be upon him) used to seek Allah's Refuge against five things of which was old age as was reported in Sahih Al Bukhari.
