And unto Midian (We sent) their brother Shu'eyb. He said: O my people! Serve Allah. Ye have no other Allah save Him! And give not short measure and short weight. Lo! I see you well-to-do, and lo! I fear for you the doom of a besetting Day.
Surah Hud(11:84)
Sahih al-Bukhari
Fasting
Chapter: Should it be said "Ramadan" or "the month of Ramadan"? And whoever thinks that both are permissible
Narrated Ibn `Umar:
I heard Allah's Messenger (ﷺ) saying, "When you see the crescent (of the month of Ramadan), start fasting, and when you see the crescent (of the month of Shawwal), stop fasting; and if the sky is overcast (and you can't see it) then regard the month of Ramadan as of 30 days."
Sahih al-Bukhari 1900
