Make a recommendation for him, and you would get the reward. Allah, however, gives the verdict through the tongue of His Apostle what He likes most.
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا أَتَاهُ طَالِبُ حَاجَةٍ أَقْبَلَ عَلَى جُلَسَائِهِ فَقَالَ اشْفَعُوا فَلْتُؤْجَرُوا وَلْيَقْضِ اللَّهُ عَلَى لِسَانِ نَبِيِّهِ مَا أَحَبَّ
Whenever a beggar or a person in need came to the Prophet, the Prophet would say "Help and recommend him and you will receive the reward for it, and Allah will bring about what he will through His Prophet's tongue
عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ إِذَا أَتَاهُ السَّائِلُ أَوْ صَاحِبُ الْحَاجَةِ قَالَ اشْفَعُوا فَلْتُؤْجَرُوا وَلْيَقْضِ اللَّهُ عَلَى لِسَانِ رَسُولِهِ مَا شَاءَ
Whenever a beggar or a person in need of something came to the Prophet ﷺ , he used to say (to his companions), "Intercede (for him) and you will be rewarded for that, and Allah will fulfill what He will through His Apostle's tongue."
كَانَ النَّبِيُّ ﷺ إِذَا أَتَاهُ السَّائِلُ وَرُبَّمَا قَالَ جَاءَهُ السَّائِلُ أَوْ صَاحِبُ الْحَاجَةِ قَالَ اشْفَعُوا فَلْتُؤْجَرُوا وَيَقْضِي اللَّهُ عَلَى لِسَانِ رَسُولِهِ مَا شَاءَ
[Machine] "We were sitting with the Prophet Muhammad ﷺ , and a questioner asked him. The Messenger of Allah ﷺ said, 'Intercede and you will be rewarded, and let Allah decide on the tongue of His Prophet what He loves.'"
كُنَّا جُلُوسًا عِنْدَ النَّبِيِّ ﷺ وَإِنَّهُ سَأَلَهُ سَائِلٌفَقَالَ رَسُولُ اللهِ ﷺ اشْفَعُوا تُؤْجَرُوا وَلْيَقْضِ اللهُ ﷻ عَلَى لِسَانِ نَبِيِّهِ مَا أَحَبَّ
Make intercession to me, you will be rewarded, for Allah decrees what he wishes by the tongue of his prophet. (Using translation from Abū Dāʾūd 5131)
جَاءَ سَائِلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ رَسُولُ اللهِ ﷺ اشْفَعُوا فَلْتُؤْجَرُوا وَلْيَقْضِ اللهُ عَلَى لِسَانِ نَبِيِّهِ مَا شَاءَ
