Musnad Ahmed: Hadith 2674

When alcohol was forbidden, some people said: O Messenger of Allah, (what about) our companions who died and who used to drink it? Then the words were revealed: “Those who believe and do righteous good deeds, there is no sin on them for what they ate (in the past)" (al-Ma’idah 5:93). And when the qiblah was changed, some people said: O Messenger of Allah, (what about) our companions who died and who used to pray facing Jerusalem? Then the words were revealed: "And Allah would never make your faith (prayers) to be lost (i.e. your prayers offered towards Jerusalem)" (al-Baqarah 2:143).
