[Machine] The Messenger of Allah ﷺ passed by a man who was saying, "O most merciful of the merciful." So the Messenger of Allah ﷺ said to him, "Ask for surely Allah has looked at you." Al-Fadl bin Isa al-Raqashi is the one who said this, and I fear that his (i.e., the man's) uncle Yazid bin Aban said it. However, I have found a witness for him in the hadith of Abu Umamah al-Bahili.  

مَرَّ رَسُولُ اللَّهِ ﷺ بِرَجُلٍ وَهُوَ يَقُولُ يَا أَرْحَمَ الرَّاحِمِينَ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ «سَلْ فَقَدْ نَظَرَ اللَّهُ إِلَيْكَ» الْفَضْلُ بْنُ عِيسَى هُوَ الرَّقَاشِيُّ وَأَخْشَى أَنْ يَكُونَ عَمُّهُ يَزِيدَ بْنَ أَبَانَ إِلَّا أَنِّي قَدْ وَجَدْتُ لَهُ شَاهِدًا مِنْ حَدِيثِ أَبِي أُمَامَةَ الْبَاهِلِيِّ
