Musnad Ahmad 8479

Translation

✧ Two things do not combine in the Fire such that one harms the other: a Muslim who kills a disbeliever, then the Muslim remains steadfast and draws near [to truth]. Two things do not combine in the belly of a servant: dust in the path of Allah and the smoke of Hellfire. Two things do not combine in a servant's heart: faith and miserliness.
