The Juristic Office at the Institution of the late Religious Authority, His Eminence, Grand Ayatollah Sayyed Muhammad Hussein Fadlullah (ra) declared in a statement that Saturday, May 27, 2017 is the first day of the month of Ramadan of the year 1438 AH. The declaration of the beginning of the holy month Ramadan has been based on the jurisprudential edict of the late Religious Authority, His Eminence, Grand Ayatollah Sayyed Muhammad Hussein Fadlullah (ra).
The statement includes the followings:
The new crescent (central conjunction) for the month of Ramadan 1438 AH will be born on Thursday, May 25, 2017 at 19:44 pm (GMT) that is at 22:44 pm Beirut time. On the evening of this day (Thursday), the crescent cannot be sighted, neither by the naked eye nor by the aid of telescopes in any region in the world. Hence, Friday marks the thirtieth of the month of Sha‘aban, and Saturday, May 27, is the first of the month of Ramadan in the eastern and western hemispheres.
On the evening of Friday (Saturday eve), the crescent can be sighted by the naked eye easily in North America, South America and most of the regions of Africa, as shown in Figure 1. It can also be sighted by the naked eye, provided that the sky is clear, in some of our Arab and Muslim countries, and by the aid of telescopes in some others, as shown in Figure 1 as well[i].
We congratulate the Muslims on the beginning of this generous month flourished with mercy, forgiveness and spirituality. We invoke Allah, the Most Exalted, to bring about all the good, blessings and mercy to all Muslims and grant them all what is necessary to preserve their dignity and steadfastness and to guide them to what makes unity and peace prevail, He is All-Hearing and Responsive.
