The Prophet ﷺ asked him, "What is your name?"He replied, "Hazn."The Prophet ﷺ said, "You are Sahl."He answered, "No. Sahl is something trodden upon and treated with contempt."Saeed said, "So I expected that hardship would afflict us after him."
حدثنا أحمد بن صالح حدثنا عبد الرزاق عن معمر عن الزهري
أن النبي ﷺ قال له ما اسمك قال حزن قال أنت سهل قال لا السهل يوطأ ويمتهن قال سعيد فظننت أنه سيصيبنا بعده حزونة
