There was a Jewish boy who used to serve the Prophet ﷺ . He fell ill, so the Prophet ﷺ visited him. The Prophet ﷺ said, "Say, 'I bear witness that there is no god but Allah and that you are the Messenger of Allah.'" The boy looked at his father and his father told him to say what Muhammad is telling him. When the boy died, the Prophet ﷺ said, "Pray for your brother" or he said, "Pray for him."

أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ قَالَ حَدَّثَنَا شَرِيكٌ عَنْ عَبْدِ اللهِ بْنِ عِيسَى عَنْ عَبْدِ اللهِ بْنِ جَبْرٍ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ

كَانَ غُلَامٌ يَهُودِيٌّ يَخْدُمُ النَّبِيَّ ﷺ فَمَرِضَ فَعَادَهُ النَّبِيُّ ﷺ فَقَالَ «قُلْ أَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللهَ وَأَنَّكَ رَسُولُ اللهِ» فَنَظَرَ الْغُلَامُ إِلَى أَبِيهِ فَقَالَ قُلْ مَا يَقُولُ لَكَ مُحَمَّدٌ فَقَالَ فَلَمَّا مَاتَ قَالَ رَسُولُ اللهِ ﷺ «صَلَّوْا عَلَى أَخِيكُمْ» أَوْ قَالَ «صَلَّوْا عَلَيْهِ»
