the Messenger of Allah said: What is wrong with people who play with the limits imposed by Allah, and one of them says: "I divorce you, I take you back, I divorce you?" (Using translation from Ibn Mājah 2017)

قَالَ رَسُولُ اللَّهِ ﷺ «مَا بَالُ أَحَدِكُمْ يَلْعَبُ بِحُدُودِ اللَّهِ يَقُولُ قَدْ طَلَّقْتُ قَدْ رَاجَعْتُ؟! »
