Difference of opinion in Juristic Issue cannot divide the Ummah

Shaykh Saalih al-Fawzaan (may Allaah preserve him) said:

“…So nothing can unite the people except the sound creed. But if they should differ in their creed, they will never be united forever. As for difference of opinion in juristic issues that are based on legal deductions to which the evidences may point, such will have no [negative] effect on the Muslim Ummah; it will not bring about division and enmity because such deductions are within latitude.

However, the differences concerning the ‘Aqidah in unacceptable; the differing party will never be united upon it. People who differ in ‘Aqidah will never be united, no matter the attempt of whoever (attempts to unite them) because he wants to bring opposing things together; and it is impossible to bring opposing or contradicting things together.
