Qibla by the Sun
Verify your qibla with nothing but a shadow — the exact minutes the sun stands on your qibla line, and the days it stands over the Kaaba itself.
How to use
- Stand a straight stick vertically on level ground (or use a hanging plumb line).
- At the shown minute, mark the shadow's line.
- The shadow points away from (or toward) the qibla as labelled — pray along that line.
