Prophet Musa (a.s) was once walking along the sea shore when a fisherman came by and prostrated himself before the Sun, uttering words of polytheism. Then he threw his fishing net in (to the sea) and drew it out filled (with fish). Then he threw it in again and once again it came out full. Once more he repeated this and once again it came out full until he was satisfied then he departed. Then another man came along, performed the ablution and stood in prayer, praising and glorifying Allah. Then he flung his net in but drew it back empty. So he repeated it and again he met with no success. Once again, he threw his net in and this time he caught a small fish. So, he praised and thanked Allah and went off. Seeing this, Musa (a.s) called out, 'O Lord! When Your servant came along and denied You, praying to the Sun and uttering blasphemy, his net was filled in with fish repeatedly until he was satisfied and left. And when Your believing servant came along, performed the ablution, prayed, glorified, praised and supplicated to You and then threw his net in, he received nothing but a small fish?' So, Allah [M.G] revealed to him, 'O Musa! Look to your right.' Musa looked and it was revealed to him what Allah [M.G] had set aside (in reward) for the believing servant. Then it was said to him, 'O Musa, now look to your left.' And he saw what (punishment) was awaiting the disbelieving servant. Then Allah [M.G] spoke, 'O Musa, (in reality) the one whom I gave did not benefit anything and nor did the one I denied lose anything.'' O Lord!' responded Musa (a.s), '(Indeed) it is the duty of all that know You to be content with whatever You do (for them).'
