Riyad-us-Saliheen 904
Sa'd bin Abu Waqqas (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) visited me during my illness and supplicated, "O Allah! Cure Sa'd. O Allah! Cure Sa'd. O' Allah! Cure Sa'd."
[Muslim]
To pray for the health and recovery of the patient, particularly uttering his name, is commendable. Furthermore, one should repeatedly pray to Allah and beseech Him with supplication till He responds.
