Hadith 4:133
'Abd al-Wahhab al-Thaqafi narrated to us, from Ayyub, from Ibn Sirin, from 'Ubaydah, who said: I asked him about the saying of the Exalted: "So whoever among you witnesses the month, let him fast it." He said: "Whoever witnesses its beginning, let him fast its end. Do you not see His saying, the Exalted: 'So whoever among you witnesses the month, let him fast it'?"
