Shama-il Tirmidhi Chapter 46, Hadith Number 10 (322).

Yusuf bin ‘Abdullah bin Salaam Radiyallahu ‘Anhu reports: “Rasulullah Sallallah ‘Alayhi Wasallam chose for me the name Yusuf. He put me in his lap and passed his mibaarak hand on my head'”.

Commentary
In this we find the high character of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam and his love for little children. The height of humbleness is that he did not avoid putting infants on his lap. In a hadith it is stated that he (Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam) also made dua of barakah for me. From this hadith it is evident that children were taken to the pious elders and were asked to choose a name for them. In other ahaadith it has also been related that the Sahaabah Radiyallahu ‘Anhum took their new born infants to Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam.
