Yahya related to me from Malik that Humayd ibn Qays al-Makki said, "A man came to the Messenger of Allah ﷺ with the two sons of Jafar ibn Abi Talib. He said to their nursemaid, 'Why do I see them so thin?' Their nursemaid said, 'Messenger of Allah, the evil eye goes quickly to them. Nothing stops us from asking someone to make incantations (using ayats of Qur'an) for them, except that we do not know what of that would agree with you.' The Messenger of ,Allah ﷺ said, 'Make incantations for them. Had anything been able to precede the decree, the evil eye would precede it.' "  

أَنَّهُ قَالَ دُخِلَ عَلَى رَسُولِ اللَّهِ ﷺ بِابْنَىْ جَعْفَرِ بْنِ أَبِي طَالِبٍ فَقَالَ لِحَاضِنَتِهِمَا مَا لِي أَرَاهُمَا ضَارِعَيْنِ فَقَالَتْ حَاضِنَتُهُمَا يَا رَسُولَ اللَّهِ إِنَّهُ تَسْرَعُ إِلَيْهِمَا الْعَيْنُ وَلَمْ يَمْنَعْنَا أَنْ نَسْتَرْقِيَ لَهُمَا إِلاَّ أَنَّا لاَ نَدْرِي مَا يُوَافِقُكَ مِنْ ذَلِكَ فَقَالَ رَسُولُ اللَّهِ ﷺ اسْتَرْقُوا لَهُمَا فَإِنَّهُ لَوْ سَبَقَ شَىْءٌ الْقَدَرَ لَسَبَقَتْهُ الْعَيْنُ
