Question: What is the ruling regarding seeking and [then] accepting help from the disbelievers?
Response: This depends [on a number of issues].
If there is no risk that seeking or accepting their help will have a harmful impact on the religious commitment of the one who asks for or accepts their help, then there is no harm in that. However, if there is any risk involved, then it is not permissible to ask for their help or to accept it – [this being] in accordance with the Sharee’ah evidences which indicate that it is obligatory to avoid [all] that which Allaah has forbidden and to keep away from that which will earn the wrath of Allaah.
It was reported that the Prophet (sal-Allaahu ‘alayhi wa sallam) accepted gifts from some of the mushrikoon whilst not from others. The wisdom behind that was what we have [already] mentioned [above], as was stipulated by the scholars.
And Allaah is the Expounder of success. And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet (sal-Allaahu ‘alayhi wa sallam) and his family and his companions.
