It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said to me: "If you fast one day, you will receive the reward of ten." I requested an increase in this, so he said: "If you fast two days, you will receive the reward of nine." I requested further increase, so he said: "If you fast three days, you will receive the reward of eight fasts."
