During the last days of his life, our beloved messenger (Peace and blessings of Allah be upon him) would wet his fingers with water and then wipe them on his blessed face to reduce the severity of fever. Mea nwhile whenever he would hear the call for prayer, he would offer his prayers while lying on the bed.
Similarly once Hadhrat Fariduddin Masood Ganj Shakar(May Allah’s Mercy be upon him) was having periods of faintness due to ailment and physical weakness but every time when he attained his senses, he would ask his followers if he had offered the prayer or not. The followers would confirm that he had offered the prayers. Upon this he would say, ‘I am not sure if it was accepted or not and then he started offering it again. Then during the prayer he would again become fainted but whenever he would get his senses, he would ask again the same question and would start his prayers again. Similarly he would attempt to offer each prayer several times. (Ahmed Mahboob)
