[Machine] He was with the Prophet ﷺ in some of his battles, and they passed by a place called Ghadir, so he performed ablution in it. He was a man with a good physique, and another man from the Ansar passed by him and said, "I have never seen anyone like him today, nor have I seen a hidden mark of a skin that I marvel at his creation." He was rushed to the Prophet ﷺ and he asked him, and he informed him of what the Ansari man said. The Messenger of Allah ﷺ said, "What prevents any of you, when he sees something in his brother that he admires in himself or his wealth, from blessing him? Verily, the evil eye is true."  

الطبراني:٥٥٨١حَدَّثَنَا الْحُسَيْنُ بْنُ إِسْحَاقَ التُّسْتَرِيُّ ثنا يَحْيَى الْحِمَّانِيُّ وَجُبَارَةُ بْنُ مُغَلِّسٍ قَالَا ثنا عَبْدُ الرَّحْمَنِ بْنُ الْغَسِيلِ حَدَّثَنِي مَسْلَمَةُ بْنُ خَالِدٍ الْأَنْصَارِيُّ عَنْ أَبِي أُمَامَةَ بْنِ سَهْلِ بْنِ حُنَيْفٍ عَنْ أَبِيهِ

أَنَّهُ كَانَ مَعَ النَّبِيِّ ﷺ فِي بَعْضِ غَزَوَاتِهِ فَمَرَّ بِغَدِيرٍ فَاغْتَسَلَ فِيهِ وَكَانَ رَجُلًا حَسَنَ الْجِسْمِ فَمَرَّ بِهِ رَجُلٌ مِنَ الْأَنْصَارِ فَقَالَ مَا رَأَيْتُ كَالْيَوْمِ وَلَا جَلْدَ مُخَبَّأَةٍ تَعَجُّبًا مِنْ خَلْقِهِ فَلُبِطَ بِهِ وَحُمِلَ مَحْمُولًا إِلَى النَّبِيِّ ﷺ فَسَأَلَهُ فَأَخْبَرَهُ بِمَا قَالَ الْأَنْصَارِيُّ فَقَالَ مَرَّ بِي فُلَانٌ فَقَالَ كَذَا وَكَذَا فَقَالَ رَسُولُ اللهِ ﷺ «مَا يَمْنَعُ أَحَدُكُمْ إِذَا رَأَى مِنْ أَخِيهِ مَا يُعْجِبُهُ مِنْ نَفْسِهِ أَوْ فِي مَالِهِ أَنْ يُبَرِّكَ عَلَيْهِ فَإِنَّ الْعَيْنَ حَقٌّ»
