باب اسْتِحْبَابِ الرُّقْيَةِ مِنَ الْعَيْنِ وَالنَّمْلَةِ وَالْحُمَةِ وَالنَّظْرَةِ ‏‏
Sahih Muslim 2198

Jabir b. 'Abdullah reported that Allah's Apostle (ﷺ) granted sanction to the family of Hazm for invocation (in mitigating the effect of the poison of) the snake, and, he said -to Asma' daughter of 'Umais:

What is this that I see the children of my brother lean? Are they not fed properly? She said: No, but they fall under the influence of an evil eve. He said: Use invocation. She recited (the words of invocation before him), whereupon he (by approving them) said: Yes, use this invocation for them.
حَدَّثَنِي عُقْبَةُ بْنُ مُكْرَمٍ الْعَمِّيُّ، حَدَّثَنَا أَبُو عَاصِمٍ، عَنِ ابْنِ جُرَيْجٍ، قَالَ وَأَخْبَرَنِي أَبُو الزُّبَيْرِ، أَنَّهُ سَمِعَ جَابِرَ بْنَ عَبْدِ اللَّهِ، يَقُولُ رَخَّصَ النَّبِيُّ صلى الله عليه وسلم لآلِ حَزْمٍ فِي رُقْيَةِ الْحَيَّةِ وَقَالَ لأَسْمَاءَ بِنْتِ عُمَيْسٍ ‏"‏ مَا لِي أَرَى أَجْسَامَ بَنِي أَخِي ضَارِعَةً تُصِيبُهُمُ الْحَاجَةُ ‏"‏ ‏.‏ قَالَتْ لاَ وَلَكِنِ الْعَيْنُ تُسْرِعُ إِلَيْهِمْ ‏.‏ قَالَ ‏"‏ ارْقِيهِمْ ‏"‏ ‏.‏ قَالَتْ فَعَرَضْتُ عَلَيْهِ فَقَالَ ‏"‏ ارْقِيهِمْ ‏"‏ ‏.‏
