What is the ruling on saying: "Do not leave" to Ramadan, and "The matter is in my hands," and "Be the first"? And is saying "Hijaab is not beautiful" disbelief (kufr)? And is it permissible to say that ruling by other than what Allah has revealed is good, or [is it permissible to] backbite negligent rulers and ministers?

The questioner is advised not to ask excessive, unnecessary, or hypothetical questions. Regarding the questions presented: There is no harm in saying "Do not leave" to Ramadan, as it expresses love for the month due to the good it contains. Similarly, there is no harm in saying "The matter is in my hands" or "Be the first," because Allah has granted humans will and strength, and they are enjoined to take means. The objector's objection to the form of hijab is not disbelief (kufr). Ruling by other than what Allah has revealed ranges between major and minor disbelief, and believing it to be permissible is disbelief. As for backbiting rulers or negligent ministers, it is religiously forbidden like any other backbiting, unless there is a legitimate religious benefit or the transgressor openly declares his transgression.
