Selected Qur'an Chapters, Ulumul Hadith and the Prophet's Reforms

Selected chapters teach faith, ethics and worship. Ulumul hadith is the study of hadith: the chain of narrators (isnad) and text (matn), and grading as sahih (authentic), hasan (good) and da'if (weak). The Prophet (PBUH) introduced reforms: ending idolatry, infanticide and usury, giving women rights and uniting people on faith not tribe. Hadith teaches us to make intentions sincere and choose good friends.
