When Messenger of Allah ﷺ fell ill, Gabriel used to recite this: "In the name of Allah, may He cure you from all kinds of illnesses and safeguard you from the evil of a jealous one when he feels jealous and from the evil influence of eye."
عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ كَانَ إِذَا اشْتَكَى رَسُولُ اللَّهِ ﷺ رَقَاهُ جِبْرِيلُ قَالَ بِاسْمِ اللَّهِ يُبْرِيكَ وَمِنْ كُلِّ دَاءٍ يَشْفِيكَ وَمِنْ شَرِّ حَاسِدٍ إِذَا حَسَدَ وَشَرِّ كُلِّ ذِي عَيْنٍ
When Messenger of Allah ﷺ fell ill, Gabriel used to recite this: "In the name of Allah, may He cure you from all kinds of illnesses and safeguard you from the evil of a jealous one when he feels jealous and from the evil influence of eye." (Using translation from Muslim 2185)
عَنْ عَائِشَةَ كَانَ النَّبِيُّ ﷺ إِذَا اشْتَكَى رَقَاهُ جِبْرِيلُ عَلَيْهِ السَّلَامُ فَقَالَ بِسْمِ اللهِ أَرْقِيكَ مِنْ كُلِّ دَاءٍ يَشْفِيكَ مِنْ شَرِّحَاسِدٍ إِذَا حَسَدَ وَمِنْ شَرِّ كُلِّ ذِي عَيْنٍ
