Sayyiduna Abu Umamah (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say: "There are six things; whoever comes with even one of them will come on the Day of Resurrection with a covenant. Each one of them will say: He used to act in prayer, zakah, Hajj, fasting, fulfilling the trust, and maintaining ties of kinship."
