Shaykh Bin Baz said, “…There is nothing wrong with seeking help of the enemies who advocate the Muslims and are able to achieve victory when the latter fear to be defeated.
The Prophet (peace be upon him), the best of creation, sought the help of Al-Mut`im ibn `Ady who was a Kafir (disbeliever) when Abu Talib the Prophet’s uncle died. Al-Mut`im, who was a popular and powerful figure, offered protection to him. When Abu Talib died, the Prophet (peace be upon him) went to Al-Ta’if to call its people to Islam. He (peace be upon him) was not able to return Makkah fearing from the people of Makkah. He sought the protection of Al-Mut`im ibn `Ady, a pagan chief who responded favorably and extended him the protection.
When the Prophet (peace be upon him) needed a guide to show him the way to Al-Madinah, he hired one of the pagans to guide him to Al-Madinah because he was sure of the latter’s honesty.
When the Prophet (peace be upon him) was in need of the Jews after the conquest of Khaybar, they were assigned to take care of the palms and the fields. They agreed that the harvest is to be divided in halves between them and the Muslims. That was because the Muslims were busy in Jihad. Although there is hostility between the Jews and Muslims, he (peace be upon him) assigned them to take care of the palms and fields of Khaybar when there was a need for that.
There is nothing wrong with seeking the help of the enemy when the latter is in favor of us against our enemies.
We can benefit from an enemy until Allah helps us combat the other enemy and force him out of the country. The case is clear for those who know the proofs of Shari`ah and the oppressor’s state, acts of transgression and the great danger he may bring…”

(MY WORDS – Abdul Kareem Ibn Ozzie – This article is about seeking help from the kuffar against transgressive Muslim groups.
However Shaykh Bin Baz in another very long article has discussed the issue of seeking help from kuffar against other kuffar. In that article he has pointed out it is halaal to do so with evidences.
But he has also made it clear that on that issue the classical scholars have differed over it.
Some never allow Muslims to seek help from the kuffar based on evidences some do allow it but with conditions based on evidences.
Those that do allow allying with kuffar against other kuffar are split into two groups, due to each group holding different conditions for this type of allegiance to be permissible, though they both agree it is halaal to form this type of allegiance with kuffar.)
