<<يَأَيُّهَا النَّاسُ قَدْ جَآءَتْكُمْ مَّوْعِظَةٌ مَّن رَّبِّكُمْ وَشِفَآءٌ لِّمَا فِى الصُّدُورِ وَهُدًى وَرَحْمَةٌ لِّلْمُؤْمِنِينَ >>
O mankind! There has come to you a good advice from your Lord (i. e. the Qur'an, enjoining all that is good and forbidding all that is evil), and a healing for that (disease of ignorance, doubt, hypocrisy and differences) which is in your breasts, ـ a guidance and a mercy (explaining lawful and unlawful things) for the believers (10:57).
