Is the statement: "Read to my small heart from the chapter of life whatever is made easy for you" considered an offense to the Qur'an?

If your cousin is not known for evil, then you should not think ill of him, especially if he did not quote a Quranic verse verbatim in his romantic poetry. The basic principle is that if a statement can be interpreted in multiple ways, it should not be interpreted negatively, and averting Hadd punishments from Muslims takes precedence. Nevertheless, the term "Surah" should not be applied to anything other than the Qur'an, and it is not permissible to use sacred Quranic terminology in romantic poetry, as this contradicts the chastity that the Qur'an calls for. The poet and others should be careful with their words and avoid anything that might lead to negative assumptions, and they should use their talent to support Islam.
