All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
Scholars held different opinions regarding the obligation of making up for the obligatory prayers that were missed deliberately. There is no harm on you in following the opinion that it is not obligatory to make up for them. This was the opinion chosen by Shaykh Al-Islam Ibn Taymiyyah.
Scholars also held different opinions regarding the obligation of making up for the obligatory prayer if one missed any of its pillars or conditions out of ignorance. The chosen opinion by Shaykh Al-Islam Ibn Taymiyyah is that one is not obliged to make up for those prayers, and this opinion is supported by strong evidence. There is no harm on you in following this opinion and acting upon his fatwa.
If you choose to make up for those prayers, then the manner of doing that is to make up for them according to your ability such that it does not cause you physical harm or affect your livelihood. The Maalikis held that it is sufficient to make up for the missed prayers of two days with each current day; you may act upon this opinion if it is easier for you. For more benefit, please refer to fatwa 334915.
Allah knows best.
