This is because Allah has never changed a favor which He has conferred upon a people until they change their own condition; and because Allah is Hearing, Knowing;
"Wancan ne, dõmin lalle ne, Allah bai kasance Mai canza wata ni'ima wadda ya ni'imtar da ita a kan wasu mutãne ba fãce sun sãke abin da yake ga rãyukansu, kuma dõmin lalle Allah ne Mai jĩ, Masani."
