Hadith on Enormities: Worst sins are usury, slander, cutting off family

Sa’id ibn Zayd reported: The Prophet, peace and blessings be upon him, said, “Among the worst kinds of usury is to disparage the honor of a Muslim without right. Verily, this womb is derived from the Most Merciful. Whoever severs its family ties, Allah will forbid him from entering Paradise.
