Is it permissible to make up missed prayers for several years without arranging the years, such as by starting with making up the prayers of the current year and then making up those of the previous years?

Practicing masturbation does not necessitate ghusl (definition) (ritual bath) unless semen is discharged. If no semen is discharged, the prayer is valid. The same applies if one doubts whether semen was discharged. However, if one is certain of its discharge, ghusl becomes obligatory. As for one who prayed ignorantly without performing ghusl, the majority of scholars hold that they must repeat the prayer. The Malikis stipulate that it must be made up in sequential order, meaning the prayer that was missed first should be prayed first. Some have said that the missed prayer should be specified by its day and time. We hold that sequential order is recommended but not obligatory, and it is permissible to make up a prayer from this year before one from a previous year.
