How should one make up the salatul ayaat missed during the whole lifetime with respect to estimating their numbers and any possible short method for lowering the burden and yet fulfilling the obligation?
If one is aware of a partial eclipse when they occurred and did not perform Salat al-ayat, he must make them up. If one was not aware when they occurred, he does not need to make them up. If one was aware of a full eclipse, whether he was aware of it or not, he must make it up. One may resort to reliable sources that archive past eclipses
