Are you asking for examples how to use "if" and "but" in English or are you asking how to use the phrase "no ifs, ands or buts" in English? Here are examples for use of "if" and "but" (and there are many uses). If you study more, you will do better in school. I would study more, but I don't have time. Here is an example of the latter use. The mom told her son that he was going to take a bath tonight and she didn't want to hear any ifs, ands or buts about it. It means that the mom doesn't want to hear any excuses from her son and that her son is definitely going to take a bath tonight - period.
