Are these words
ولك عندي بكل يوم وليلة أجر صديق
an authentic addition to the narration on your website found here?
No. ‘Allamah Dhahabi (rahimahullah) has declared this version a fabrication.
(Mizanul I’tidal, vol. 2 pg. 115, number: 2967 and Lisanul Mizan, vol. 4 pg. 29)
The following version should be quoted instead:
Yazid ibn Maysarah (rahimahullah) says:
“Allah Ta’ala boasts to the angels regarding a youngster who is engaged in the ‘ibadah of Allah. Allah says, ‘Look at my servant, he has given up his desires for my sake.'”
(Az Zuhd of Imam Ahmad ibn Hambal, Hadith: 547. See here)
And Allah Ta’ala Knows best.
