بسم الله الرحمن الرحيم.
When studying and analysing the properties of each function in our bodies, we come to manifest the Merciful and Clement attributes of Allah in His creation. If we take the tears to examine, which we sometimes underestimate its significance, it becomes clarified to us how gentle and subtle Allah The Most Compassionate is to His creation.
This passage is about the function of tears from wikipedia:
" Tears brought about by emotions have a different chemical make up than those for lubrication; emotional tears contain more of the protein-based hormones prolactin, adrenocorticotropic hormone, and leucine enkephalin (a natural painkiller) than basal or reflex tears."
As stated, the chemical make up of emotional tears are special as they contain a natural pain killer. This is how Allah, The Creator, formulated them; as a means of mercy, so that when we feel sorrow we shed tears that release anti depression chemicals contained in leucine enkephalin, to wash our sorrows and griefs away. In order that at times of sorrow we don't grief to an extent of despair and attempt to take out an exaggerated decision.
Now, is it suitable after knowing all this mercy that Allah has placed in our small tear glands, that at times of prosperity when no sadness is overcoming us, that we intentionally misdirect using the blessing of sight in looking at forbidden gazes? Nay, but we should instead use them properly in reflecting on the signs of Allah and to read in the branches of knowledge that would get us closer to Him, Insha'Allah.
Alhamdu li Allah. Praise and Glory be to Allah, May Allah protect us and restrain ourselves from evil, and enlighten us about His signs in this world so that we would deeply acknowledge His Beautiful Attributes. Ameen.
