Advice is definitely beneficial, but who can give better advice than the Creator of existence?

يَا أَيُّهَا النَّاسُ قَدْ جَاءَتْكُمْ مَوْعِظَةٌ مِنْ رَبِّكُمْ وَشِفَاءٌ لِمَا
فِي الصُّدُورِ وَهُدًى وَرَحْمَةٌ لِلْمُؤْمِنِينَ

O mankind! There has come to you a good advice from your Lord (i.e. the Quran, ordering all that is good and forbidding all that is evil), and a healing for that (disease of ignorance, doubt, hypocrisy and differences, etc.) in your breasts, – a guidance and a mercy (explaining lawful and unlawful things, etc.) for the believers.

[سورة اليونس: ٥٧]
