Surah 9

Surah 9:37

"The postponement is an increase of disbelief by which those who disbelieve go astray. They make it profane (one) year, and make it sacred (another) year, to adjust the number (of months) God has made sacred, and to profane what God has made sacred. The evil of their deeds is made to appear enticing to them, but God does not guide the people who are disbelievers."
