Is the correct order in the noble Hadith "his character and his religion" or "his religion and his character," and what is the difference between "Fitnah" and "wide corruption," and why was the word "wide" used instead of "great"?

The hadith cited by the questioner was narrated by Ibn Majah and Al-Hakim from Abu Hurayrah, may Allah be pleased with him, with the wording: "If someone whose character and religious commitment you approve comes to you, then marry him. If you do not do so, there will be fitnah on earth and widespread corruption." It was also narrated by Al-Tirmidhi with the wording: "If someone whose religious commitment and character you approve proposes to you, then marry him."

The meaning of the hadith is that character and religious commitment are the most important qualities to seek in a prospective spouse. Good companionship revolves around character, and fulfilling rights revolves around religious commitment. They are inseparable. There is no issue with character being mentioned before religious commitment in some wordings of the hadith.

His saying: "If you do not do so, there will be fitnah on earth and widespread corruption" means that if you do not marry off those whose character and religious commitment you approve, and instead desire those of noble lineage and wealth, then that will lead to fitnah, an increase in zina (unlawful sexual intercourse), and the spread of widespread corruption.
