Ibn `Abbas (May Allah be pleased with them) reported: The Prophet (PBUH) said, "He who visits a sick person who is not on the point of death and supplicates seven times: As'alullahal- `Azima Rabbal-`Arshil- `Azimi, an yashfiyaka (I beseech Allah the Great, the Rubb of the Great Throne, to heal you), Allah will certainly heal him from that sickness.''
[Abu Dawud and At-Tirmidhi] .
Commentary: There is always a great certainty that Allah will respond to a supplication which springs from a sincere, veracious heart. One should, therefore, pray for a patient with full conviction and reassurance of heart. Moreover, the Prophet's prayers have special effect and grace and therefore their original wordings should be uttered.
