What should a committed girl do who suffers from kidney failure, has stopped praying for three months due to difficult health conditions after a kidney transplant, and now feels hardness in her heart and fear regarding the missed prayers, and finds it difficult to commit to performing prayers on time?

It is permissible for a sick person to combine the prayers that share a time if he experiences hardship. So, he can combine Dhuhr with Asr, and Maghrib with Isha. This is the view of the Hanbalis, who cite the Hadith of Ibn Abbas that the Prophet (peace and blessings be upon him) combined prayers without fear, travel, or rain. This is also because Istihadah (non-menstrual vaginal bleeding) is a type of illness, and the Prophet (peace and blessings be upon him) commanded the woman experiencing Istihadah to combine prayers. As for making up missed prayers, a Muslim should strive to do so according to his ability. It is possible to make up two days' worth of prayers each day, adopting the view of the Malikis. If prayers were missed due to overwhelming circumstances and he was unable to perform them, then there is no sin upon him. However, if there was negligence, then he must repent and seek forgiveness. He is advised to be patient, listen to beneficial lectures, and keep the company of righteous people.
