Narrated Abu Hurairah that he heard the Prophet ﷺ saying, "Allah decided to test three people from Bani Isra'il. So, He sent an angel who came first to the leper and said, '(I am a traveller) who has run short of all means of living, and I have nobody to help me except Allah, and then with your help.'" Abu Hurairah then mentioned the complete narration.  

أَنَّهُ سَمِعَ النَّبِيَّ ﷺ يَقُولُ إِنَّ ثَلاَثَةً فِي بَنِي إِسْرَائِيلَ أَرَادَ اللَّهُ أَنْ يَبْتَلِيَهُمْ فَبَعَثَ مَلَكًا فَأَتَى الأَبْرَصَ فَقَالَ تَقَطَّعَتْ بِي الْحِبَالُ فَلاَ بَلاَغَ لِي إِلاَّ بِاللَّهِ ثُمَّ بِكَ فَذَكَرَ الْحَدِيثَ
