As water scarcity and crises looms large over the planet, it has become the responsibility and duty of every person to conserve water. One such step taken by me and my wife is to use condensed drain water from air conditioners stored in fresh and ‘tahir’ vessels to perform wudhu for namaz for 5 times. Is the salah offered with such wudhu valid or not keeping in view that the water is clear and nothing is mixed in it and the vessel is far from approach of animals?
بسم الله الرحمن الرحيم
Rain water is pure. If one stores rain water in some vessel and performs wudhu with it then wudhu will be valid.
