إِنَّ مِنَ الْمَعْرُوفِ أَنْ تَلْقَى أَخَاكَ بِوَجْهٍ طَلْقٍ
Translation: Among good deeds is that you meet your brother with a cheerful face.

الْمَعْرُوف includes recognized goodness and considerate conduct. Even when unable to provide money or major assistance, a person can meet others pleasantly, listen attentively, and avoid coldness. بِوَجْهٍ طَلْقٍ conveys an open, cheerful expression, not artificial flattery or mocking laughter.
أَنْ تَلْقَى uses أَنْ with a present-tense verb: “that you meet.” أَخَاكَ means “your brother.” وَجْهٍ طَلْقٍ is a noun followed by an adjective, “a cheerful face,” introduced by the preposition بِـ.
Greeting a colleague kindly, welcoming a guest pleasantly, or answering a troubled person respectfully are practical examples. They cost little but can improve relationships.
