4-52 Muhammad ibn Musa ibn al-Mutevakil - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted Muhammad ibn Ahmad, on the authority of Muhammad ibn Sin’an, on the authority of Muawiyah ibn Wahab that Aba Abdullah as-Sadiq (MGB) said, “Who would pledge to abide by four characteristics for whom I shall guarantee four houses in Paradise: spending in charity without fearing to become poor; being fair to the people; greeting aloud; and not arguing although you are right.”
