Mavzui markazii ejodiyoti F. Muhammadiev akhloqi hamidai insoni meboshad. Solhoi 1967-1973 silsilai hikoyahoi navi- sanda bo nomhoi «Davo», «Sudi rafiqon», «Ruzi dafni Usto Oqil», «Sozi Munavvar», «Hiyoboni Nodir», «SHabi sevum» ba vujud omadand. Navisanda insonro yaktarafa va ba yak rang tasvir namekunad. Dar tasviri u, bo vujudi jihathoi nomunosib dosh- tan, obraz kullan manfi nest. Navisanda raftori noshoistai personajhoro, chun bakhilii Muhammadmurod («Davo»), rashki bejoi Ashraf («Savdoi umr»), kasbi khudro ba meros naguzoshta- ni Usto Oqil («Ruzi dafni Usto Oqil») hunarmandona mahkum mekunad.
Usto Oqil ustoi guldast bud, aksari imorathoi zeboi deha mahsuli hunari u budand va ba qavli Abdurraufamak: «In khel ustoi hunarmand dar sad sol yo yak bor ba dunyo meoyad, yo ne». Lekin ananai neki mardumro vayron namuda, umrash az shast guzashtu yagon shogird tayyor nakard va oqibat vafot kardu hunarashro bo khud ba gur burd. Binobar in, etiqodi mardum az u kand va dar janozaash hamagi bist kas huzur doshtandu khalos.
