A student of knowledge used [to live] in his country. He then migrated to Saudi Arabia in order to safeguard his religion, fearing for himself the trials and tribulations in his country, even though the people in his country are in great need of him..”

Shaykh Ṣāliḥ al-Fawzān:

No, if a student of knowledge is needed by the Muslims in another land, then staying with them is better. Staying with them and calling them to Allāh ﷻ, enlightening them of their religion, staying with them has benefits. Calling them to Allāh ﷻ and directing them Muslims there is better than migrating to Saudi Arabia.
