Sahih Muslim 1893a
It has been narrated on the authority of Abu Mas'ud al-Ansari who said: A man came to the Messenger of Allah ﷺ and said: My riding beast has been killed, so give me some animal to ride upon. He (the Holy Prophet) said: I have none with me. A man said: Messenger of Allah, I can guide him to one who will provide him with a riding beast. The Messenger of Allah ﷺ said: One who guides to something good has a reward similar to that of its doer.
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَأَبُو كُرَيْبٍ وَابْنُ أَبِي عُمَرَ - وَاللَّفْظُ لأَبِي كُرَيْبٍ - قَالُوا حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ أَبِي عَمْرٍو الشَّيْبَانِيِّ، عَنْ أَبِي مَسْعُودٍ الأَنْصَارِيِّ، قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنِّي أُبْدِعَ بِي فَاحْمِلْنِي فَقَالَ " مَا عِنْدِي " . فَقَالَ رَجُلٌ يَا رَسُولَ اللَّهِ أَنَا أَدُلُّهُ عَلَى مَنْ يَحْمِلُهُ فَقَالَ رَسُولُ اللَّهِ ﷺ " مَنْ دَلَّ عَلَى خَيْرٍ فَلَهُ مِثْلُ أَجْرِ فَاعِلِهِ " .
