1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from ‘Abd Allah ibn Yahya al-Kahiliy from abu Ahmad al-Kahiliy -I think I met him who has said the following: “I once asked him (the Imam) (a.s.), about a girl who is not a relative to me who holds me and I carry her and kiss her. He (the Imam) said, ‘When she becomes six years old then you must not place her in your lap.’”
