The Prophet ﷺ received Ja'far ibn AbuTalib, embraced him and kissed him between both of his eyes (forehead).  

أبو داود:٥٢٢٠حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ عَنْ أَجْلَحَ عَنِ الشَّعْبِيِّ

أَنَّ النَّبِيَّ ﷺ تَلَقَّى جَعْفَرَ بْنَ أَبِي طَالِبٍ فَالْتَزَمَهُ وَقَبَّلَ مَا بَيْنَ عَيْنَيْهِ
