It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "If any Muslim visits a sick person whose time of death has not yet come and says seven times: «أَسْأَلُ اللّٰهَ الْعَظِيمَ رَبَّ الْعَرْشِ الْكَرِيمِ أَنْ يَشْفِيَهُ» 'I ask Allah, the Lord of the Mighty Throne, to grant you healing,' then Allah Almighty grants him well-being."
