What is the established evidence for the obligation to make up intentionally missed prayers, and what is the ruling on one who intentionally abandoned prayer, then repented and performed Hajj? And does the hadith, "Whoever performs Hajj for the sake of Allah and does not engage in sexual intimacy or commit sins will return as the day his mother gave birth to him," suffice him from making up the prayers?

The majority of scholars are of the opinion that it is obligatory to make up for intentionally missed prayers, arguing that if making them up is obligatory for one who missed them due to forgetfulness or sleep, it is even more so for one who intentionally abandoned them. They based their reasoning on the Prophet’s (peace be upon him) saying: "Whoever forgets a prayer, let him pray it when he remembers it, for there is no expiation for it except that. And establish prayer for My remembrance." They see this as an admonition by way of the lesser case for the greater case: if making up the prayer is obligatory for the forgetful person, who is not sinful, then it is even more so for the intentional transgressor. Repentance or an accepted Hajj do not waive the obligation to make up for missed prayers, because making up prayers falls under the category of rights, not sins that are remitted by repentance.
