I came across this remarkable sight and site recently right before the three day water cut in the Klang Valley while driving back home from Singapore.
Generally I’ve always been with how the North South Expressway Company designed their rest stops, especially the prayer rooms (suraus/musallas). By this I mean a design that is suitable to our humid weather and use which involves a lot of water.
This in mind, Muslim minority Singapore are miles, miles ahead in designing their mosques compared to their Malaysian neighbours.
Firstly Singapore mosques do not use air conditioning, and yet manage (very) well. Secondly, they’ve adopted modern basic technology that assists worshippers practicing more of the sunnah, even if the intended purpose was water management for non Godly sake.
This small highway rest stop in Senawang (Malaysia) did well too.
Besides the standard high ceiling and air outlets through it, and the sufficient distance between ablution area to the prayer area which all allows for less dampness and undesirable smell, it had that tall thing by the entrance.
A rain water harvesting tank, with a pipe ready for you to use.
And a waqaf (endowment) hut next to it, which although these days used for resting, it allowed for families such as myself, to still pray in congregation, and rest together without having the need for any chairs be it adults or babies.
None of this costs a great amount to build or maintain, and nor are they exclusive to Muslims only.
May those who bring benefit to others be allowed by Him to continue to do so.
