How does one make up for prayers missed for several days due to unknown excuses or their invalidation, and how does a woman pray Dhuhr and Maghrib prayers in the market, and when should she make them up if she delays them?

Whoever has neglected their prayers or performed them incorrectly must repent, learn how to pray correctly, and make up for what they missed immediately according to their ability. If the missed prayers are numerous, they should make up at least two days' worth of prayers in a single day, unless doing so would affect their ability to earn a livelihood for their family, in which case they may limit it to one day's worth of prayers. As for a prayer that was performed and conformed to the opinion of one of the scholars, it is not obligatory for them to repeat it. However, if it did not conform to anyone's opinion, then they must repeat it. A woman must perform her prayer on time wherever she is, and if that is difficult for her, she may combine two prayers. If she is unable to perform them at their prescribed time, then she must make them up whenever she is able.
