When we cry, our tears liberate certain toxics from our body. Science has proven that when we cry at late night, like at about 2-5 am, that’s when the tears we produce release most of those certain toxics from our body.

And in Islam, after the 5 daily prayers, the prayer which holds the most priority is the sunnah prayer at late night (tahajjud), at about 2-5 am, too..
 
Is this a mere coincidence?? (:
