SB 8.21.33
vrtha manorathas tasya
durah svargah pataty adhah
pratisrutasyadanena
yo ’rthinam vipralambhate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Far from being elevated to the heavenly planets or fulfilling one’s desire, one who does not properly give a beggar what he has promised falls down to a hellish condition of life.
