Perhaps you should try some spelling variations:
"mohammad hassan kabir" » "mohamad hassan kabir", "muhammad hassan kabir", "mohamed hassan kabir", "mohammad hassan kassim", "mohammad hassan nabiha", "mohammad jausyan kabir"
"mohammad hossein kabir" » "mohammad hossein karimi", "mohammad hossein saberi", "mohammad hossein vahid"
"mohammad hasan kabir" » "mohammad jausyan kabir", "mohammad hasan khamis", "mohammad hasan khatib"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("mohammad hasan kabir") OR ("mohammad hossein kabir"))) or ("mohammad hassan kabir"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("mohammad hasan kabir") OR ("mohammad hossein kabir"))) OR ("mohammad hassan kabir")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mohammad hasan kabir\") OR (\"mohammad hossein kabir\"))) or (\"mohammad hassan kabir\"))".
• Removing quotes may allow a broader search: (((( mohammad hasan kabir ) OR ( mohammad hossein kabir ))) or ( mohammad hassan kabir )).
• Adding a wildcard symbol may retrieve word variants: (((("mohammad hasan kabir") OR ("mohammad hossein kabir"))) or ("mohammad hassan kabir"))*.
