It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that when the command for changing the Qiblah was revealed, the people said: O Messenger of Allah! What will happen to our companions who used to pray facing Bayt al-Maqdis and passed away in that state? Upon this, the following verse was revealed: «﴿وَمَا كَانَ اللّٰهُ لِيُضِيعَ إِيمَانَكُمْ﴾ [البقرة: 143] » "Allah is not one to waste your prayers."
