590 – Ṣāliḥ ibn Ḥarb, a mawla (client) of Banū Hāshim, narrated to me; he said: Salām ibn Abī Khubza narrated to us; he said: Nalz al-Aʿyun narrated from al-Ḥasan that he once entered his house and found some children playing on the roof. His son ʿAbd Allāh tried to stop them, but al-Ḥasan said, “Leave them alone, for play is their springtime.”
