Sayyiduna Sahl bin Sa’d (may Allah be pleased with him) narrates: The Prophet Muhammad (peace and blessings be upon him) said:“My Ummah will remain upon my Sunnah as long as they do not wait for the stars (to appear) for breaking the fast.”The narrator states: When the Prophet Muhammad (peace and blessings be upon him) was fasting, he would instruct someone to climb a high place and observe; when that person informed him that the sun had set, the Prophet Muhammad (peace and blessings be upon him) would break his fast.
