Perhaps you should try some spelling variations:
"maulana datta ur rehman" » "maulana datta ur rahman", "maulana dutta ur rehman", "maulana natta ur rehman"
"maulana patta ur rehman" » "maulana patta ur rahman", "maulana natta ur rehman", "maulana palta ur rehman", "maulana patra ur rehman"
"maulana data ur rehman" » "maulana data ur rahman", "maulana dat ur rehman"

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

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