More shuyukh have spoken against the ISNA Fiqh Council moon sighting decision to base the Islamic lunar month only on astronomical calculations (derived by their own scientists) and disregard the sunnah of sighting the actual moon with the naked eye.
I have obtained the following answers lately (InshaAllah I’ll add others as they come in):
(*) ISNA’s Recent Decision Regarding the 1st of Ramadan and the ‘Id– “… The Ulama Association of North America (UANA) unequivocally declares that lunar months should begin with sighting and not with calculation. This is the ruling of Shari‘ah and we must abide by it. ISNA’s Fiqh Council has created confusion in the minds of Muslims before due to its decisions and we implore that that they avoid doing this.” – Ulama Association of North America (UANA)which comprises of various ulama across the United States, including esteemed ulama such as Moulana Abdullah Saleem (Institute of Islamic Education, Elgin, Illinois), Imam Tahir Anwar (South Bay Islamic Association, San Jose, California), Moulana Khaja Shuaibuddin (Salt Lake City, Utah), Mufti Abdurrahman Ibn Yusuf (Islamic Society of Santa Barbara, Santa Barbara, California) and others.
(*) Islamic Shariah Council of California (USA) refutes ISNA’s fatwa on moon calculation– “The setup of a new criterion for the start of Islamic month that the moon is born before 12:00 Noon GMT is contrary to Islamic sources, practice of ummah and views of the majority of the Islamic Scholars and Ulama throughout Islamic history.” – Islamic Shariah Council of California (Signed and endorsed by the more than 40 plus prominent scholars and imams)
(*) More coming soon.
