A woman dying asking for water but the doctor banned her from drinking due to the operation she had

Q: My mother suffered severe illness that led to her death. She used to refuse to enter any hospital. However, during her last suffering, my sister, and I insisted that she must enter the king `Abdul-`Aziz hospital in Jeddah Jeddah where she underwent surgery. The examinations and scans showed that she had stomach cancer. Three days later, the cancer spread significantly throughout all the body. During that period, she asked me for water, but I refused as the doctor ordered us not to give her water until three days pass after the date of the operation. (Part No. 21; Page No. 393) She had bleeding and her consciousness was lost at times, and awakened at other times. I helped her utter the Shahadah (Testimony of Faith). During the night when she died, I slept beside her for an hour. When I woke up, she was dead. One woman told me that she saw my mother in a dream in a state of anger towards me because I rejected to give her water. My question is: Am I sinful for this act? If so, what is the Kaffarah (expiation) that I should offer? Please, advise. May Allah reward you with the best!

A: If the reality is as you have mentioned, you committed no sin concerning your mother's death. You rejected to give her water as the doctor ordered you not to do so during the said period. Thus, you did not intend her any harm, but rather you were keen to provide her with something that benefits her treatment and avoids any complications. No Kaffarah is required. As to what the woman saw in the dream, you should pay no attention to it as it is from Satan. You should fulfill her rights over you after her death by supplicating to Allah frequently to forgive her and be merciful with her, giving in charity on her behalf, and maintaining ties with her relatives and friends. (Part No. 21; Page No. 394) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
