Praise be to Allah.
We put the following question to Shaykh ‘Abd-Allaah ibn Jibreen:
Is it obligatory for non-Arabs to learn Arabic?
He, may Allaah preserve him, replied as follows:
They have to learn as much as they need for Islamic purposes, how to pronounce the words and what they mean, such as the Takbeer, al-Faatihah and al-Tasbeehaat – those that are obligatory in the prayer and for other duties.
